Kerber made her first attempt to qualify for a WTA tournament in January 2005, at the Auckland Open, falling to Janette Husárová in the final round. In 2007, she made her Grand Slam main-draw debut at the French Open where she lost to 13th seed Elena Dementieva in the opening round. Shortly after, she appeared in the main draw of a WTA tournament for the first time, in Birmingham, where she reached the third round, losing to fifth seed Marion Bartoli, who was the eventual runner-up at Wimbledon that year. The week after Birmingham, she reached her first main draw quarterfinal at the Rosmalen Open where she was beaten by eventual champion Anna Chakvetadze, and then fell to Chakvetadze once more, in the first round of Wimbledon.

Kerber achieved her first Grand Slam victory in 2008 at the Australian Open by defeating Maret Ani, before losing to 25th seed Francesca Schiavone. She also made the third round at Indian Wells where she lost to sixth seed Bartoli. Kerber did not progress much that year after that, besides winning a further two ITF titles. Her struggles would continue in 2009 as she managed just three wins in WTA main draws. She did qualify for the US Open that year, where she made the second round. She also won her 11th and final ITF title that year. She finished 2008 and 2009 respectively ranked barely outside the top 100, at No. 108 and No. 106, respectively.

At Wimbledon, she lost to youngster Laura Robson in the first round. In Dallas, the week before the US Open, she recorded a semifinal run, where she lost to Aravane Rezaï.

Kerber entered the US Open ranked world No. 92, and passed the first hurdle with a win in three sets over Lauren Davis in three sets. Next, she faced 12th seed Agnieszka Radwańska and pulled off a shock three-set victory before going on to beat both Alla Kudryavtseva and Monica Niculescu to reach her maiden Grand Slam quarterfinal. There, Kerber surprised multiple-time quarterfinalist here Flavia Pennetta in three sets to advance to the semifinal, where she lost to ninth seed and eventual champion Samantha Stosur in three sets.

After that, she reached the semifinals in Osaka where she lost to eventual champion Bartoli. She finished the year as world No. 32, her second finish in a row in the top 50.

Kerber's first tournament of 2012 was the Auckland Open where she reached the semifinals, falling to eventual runner-up Pennetta. At the Australian Open, Kerber was seeded at a Grand Slam tournament for the first time, and made the third round where she lost to fourth seed Maria Sharapova. As a result, Kerber rose to a new career-high ranking of world No. 27. She then competed in her first Fed Cup tie in almost five years, where Germany faced defending champions Czech Republic in the quarterfinals, and won her only rubber, defeating Lucie Hradecká in straight sets but the Germans lost the tie 1–3. At her next tournament was in Paris, Kerber lifted her maiden WTA singles title. After seeing off Lucie Šafářová and Niculescu to make the last eight, she upset top seed Sharapova in straight sets. Kerber then beat Yanina Wickmayer in the last four, and faced second seed Bartoli in the final, seeing off the home player in three sets to win the title. She then suffered an early loss at the Qatar Open in hands of unseeded Bulgarian Tsvetana Pironkova in the second round.

Kerber's continued her surge up the rankings through the coming three months, that culminated in her cracking the top 10 rankings for the first time in her career. She started with a semifinal appearance at the Indian Wells Open. Seeded 18th with a bye in the first round, she moved past three Americans in Sloane Stephens, Vania King and Christina McHale, the second one via a walkover. Kerber then upset eighth seed Li Na in the quarterfinals, but was stopped by world No. 1 and eventual champion Victoria Azarenka in the last four. Her ranking improved to a career-high world No. 14 as a result. In Miami, Kerber was upset in her opener by Zheng Jie. Her next stop was indoors, at the Danish Open where she was the second seed. In her opener, she struggled past Stéphanie Foretz Gacon and then defeated Anne Keothavong and fellow German Mona Barthel. After that, she defeated third seed Jelena Janković to reach her second final of the year. She won the title by defeating the top seed and defending champion Caroline Wozniacki in straight sets.

Starting off her clay season on home soil, in Stuttgart, Kerber advanced to the quarterfinals with wins over Roberta Vinci and sixth seed Wozniacki, before losing to third seed Petra Kvitová. After an early exit in Madrid, Kerber advanced to the semifinals in Rome after avenging her Stuttgart loss to Kvitová in the last eight, which ensured herself a rise to the top 10 rankings for the first time in her career. In the last four, she lost to Sharapova in straight sets. At the French Open, 10th-seeded Kerber amassed back-to-back wins here for the first time after beating Zhang Shuai and Olga Govortsova. She then beat 18th seed Pennetta in three sets before seeing off Petra Martić in the fourth round to reach the quarterfinals, where she lost to eventual runner-up Sara Errani.

Kerber continued her steady rise of 2012 on grass, firstly by posting a runner-up appearance in Eastbourne, losing to a close final to Tamira Paszek, having served for the championship in the deciding set and missing five match points. At the Wimbledon Championships, Kerber was seeded eighth. She advanced to her second Grand Slam quarterfinal in a row, this time without losing set, by beating Lucie Hradecká, Ekaterina Makarova, 28th seed Christina McHale and former world No. 1 Kim Clijsters., the latter in 49 minutes. There, she defeated fellow German and 15th seed Sabine Lisicki in three sets, having been down a break in the third. In the semifinals, she lost to Agnieszka Radwańska. This was Kerber's then most recent equal-best Grand Slam result, for another three years until Australian Open in 2016.

At the London Olympics, Kerber made her first appearance at this stage, and was seeded seventh. She defeated Petra Cetkovská and Tímea Babos first two rounds, to set up a clash with Venus Williams. There, she beat the former world No. 1 in two tiebreak sets, to make the quarterfinals where she lost to top seed and eventual bronze medallist Victoria Azarenka in straight sets. In the other disciplines, Kerber partnered Philipp Petzschner in mixed doubles and Lisicki in women's doubles, falling in the first and second rounds, respectively.

Competing at the Canadian Open to open her US Open Series campaign, Kerber lost early but bounced back at the Cincinnati Open with another strong result. First, she beat Babos and Andrea Hlaváčková to reach the quarterfinals, where she defeated Serena Williams for the first time, winning in straight sets, thus snapping Williams's 19-match winning streak. She continued with a win over Kvitová in the semifinals, to book a spot in her first Premier 5 final, but lost to Li from a set up. At the US Open, sixth-seeded Kerber won a close match against Venus Williams in the second round en route to the fourth round, but failed to defend her semifinal points from a year ago when she lost to eventual semifinalist Errani.

Kerber's next tournament was the Pan Pacific Open where she made it to the semifinals before losing to defending champion Radwańska. She also reached the quarterfinals of the China Open, but fell to eventual runner-up Sharapova. Her breakthrough season ensured herself qualification for her maiden appearance at the WTA Tour Championships. She also hit the world's top 5 rankings for the first time in her career, at world No. 5, entering the week of the season-ending championships, where she was seeded fifth. There, however, she exited the tournament in the round robin stage, without winning any matches, the losses coming in the hands of Serena Williams, Azarenka and Li. Nevertheless, Kerber ended the 2012 season at world No. 5, with 60 wins amassed throughout the season.

Kerber began 2013 at the Brisbane International where she was seeded fourth, and made the quarterfinals where she was stopped by eventual runner-up Anastasia Pavlyuchenkova. Seeded second in Sydney, Kerber made the last four but lost to another eventual runner-up once more, this time in Dominika Cibulková. She then reached the fourth round of the Australian Open, completing the set of second-week appearances at all four Grand Slams. Along the way, she defeated Elina Svitolina, Lucie Hradecká, and wildcard Madison Keys. She was subsequently defeated by 19th seed Ekaterina Makarova after struggling with a back injury.

After a dry winless spell in the Middle East, Kerber bounced back with a second consecutive semifinal result at the Indian Wells Open, where she was stopped by eighth seed Caroline Wozniacki in three sets, despite having won the first set. Like the previous year, an early exit in Miami followed suit, this time to Sorana Cîrstea. Kerber then reached her first final of 2013 in Monterrey where she was the top seed but lost to Anastasia Pavlyuchenkova in three sets.

Kerber posted strong results on clay in 2013. Firstly, on Fed Cup, she helped Germany regain its place in the World Group by winning her rubber against Bojana Jovanovski, the German eventually winning the tie 3–2. She then recorded a run to the semifinals in Stuttgart, going one round better than the previous year, where she fell in three sets to defending champion Maria Sharapova. At the Madrid Open, sixth-seeded Kerber moved into the quarterfinals here for the first time after defeating top-40 opposition in Hsieh Su-wei, Alizé Cornet and Svetlana Kuznetsova. There, she lost to Ana Ivanovic in straight sets. At the French Open, Kerber reached the fourth round for the second year in a row but did not go further this time as she was beaten by former champion Kuznetsova in three sets. She did not enjoy much success on grass next, however, as she failed to post back-to-back wins in her tournament appearances on the surface, falling at the second hurdles of both Eastbourne and Wimbledon, to Makarova and Kaia Kanepi, respectively. Having failed to defend her semifinal result at Wimbledon from the year, Kerber fell to world No. 9 in the rankings after the tournament's conclusion.

After posting a quarterfinal at the Washington Open, Kerber made her only appearance of the US Open Series in Cincinnati but lost in third round to Li Na, in a rematch of last year's championship match. At the US Open, eighth seed Kerber posted her third fourth-round result at the Grand Slams this year, and second in a row here, after defeating Hradecká, Eugenie Bouchard and 25th seed Kanepi but then lost to 18th seed Carla Suárez Navarro this time.

During the Asian swing, Kerber's form improved as she reached her second final of 2013, at the Pan Pacific Open, having defeated Ivanovic, Wozniacki and Radwańska en route, but there, she lost to Petra Kvitová in three sets. The following week at the China Open, she reached the quarterfinals where she lost to Radwańska, and then advanced into her third final of the season, at the Linz Open. There, Kerber scored her third career title, and third indoors, as she defeated two-time champion Ivanovic, thus and filling up the last spot at the WTA Tour Championships. In her second outing at the Championships, Kerber failed to get past the round robin stage, once more, with losses to Serena Williams and Kvitová. However, she did record her maiden victory at this stage by defeating Radwańska, in her second round robin match. Kerber would finish the year as world No. 9.

Kerber began 2014 the same way she did in 2013, logging in quarterfinal or better results in both Brisbane and Sydney, going one round better in the latter this time around by making the final but there, she was stunned by qualifier Tsvetana Pironkova in straight sets. She made the fourth round of the Australian Open once more, falling to 28th seed Flavia Pennetta in three sets this time around. At the Open GdF Suez, former champion Kerber made the quarterfinals where she lost to eventual champion Anastasia Pavlyuchenkova. In Fed Cup quarterfinal play against Slovakia, Kerber contributed to the German team's victory by winning both her singles rubbers, over Dominika Cibulková and Daniela Hantuchová.

At the Qatar Open, Kerber sailed into her first quarterfinal in the Middle East with wins over Karolína Plíšková and Klára Koukalová. She subsequently moved into her second final of 2014 with wins over qualifier Petra Cetkovská and fifth seed Jelena Janković. There, she lost to Simona Halep in straight sets. After a two-match losing streak across Dubai and Indian Wells, fifth-seeded Kerber made her first quarterfinal showing in Miami, where she lost to defending champion Serena Williams in straight sets.

In April, Kerber helped put her country in the Fed Cup final, with Germany taking on Australia in the last four, by winning both her singles rubbers, against Samantha Stosur and Casey Dellacqua. However, she then endured a three-match losing streak to begin her season on clay, snapping it on home soil in Nuremberg with a quarterfinal appearance, where she was beaten by Plíšková. At the French Open, Kerber made the last 16 for the second year running, falling to rising star and 18th-seeded Bouchard this time around. On grass, Kerber enjoyed better results this year, starting off with her second appearance in the championship match at the Eastbourne International but finished runner-up once more, her third of 2014, this time to youngster Madison Keys in three sets. At Wimbledon, Kerber was seeded ninth and entered the second week for the fourth Grand Slam tournament running, with victories over the likes of defeated Urszula Radwańska, Heather Watson, and previous year's semifinalist Kirsten Flipkens. In the round of 16, she prevailed over reigning French Open champion and fifth seed Sharapova in three sets to move into the second last eight showing here. There, she lost to eventual runner-up Bouchard in straight sets.

Kerber opened her US Open Series campaign in Stanford where she was the third seed. She defeated CoCo Vandeweghe in three sets in her opener, to reach quarterfinals where she saw off Garbiñe Muguruza. A win over Varvara Lepchenko, where she had to save a match point, put her in her fourth final of the year, but she had to settle for the runner-up position again, for the fourth time in 2014 when she lost to Serena Williams. After a string of early exits in Montreal and Cincinnati, Kerber made the third round of the US Open with wins over Russian qualifiers, Ksenia Pervak and Alla Kudryavtseva, but lost to unseeded youngster Belinda Bencic.

Kerber posted deep runs in Tokyo and the inaugural Wuhan Open the following month, reaching the semifinals and quarterfinals, respectively. In her final tournament of the season, Kerber made the third round of the China Open where she lost to Svetlana Kuznetsova. Kerber did not qualify for the WTA Finals in 2014 but entered the tournament as an alternate, and would finish the season ranked world No. 10. Kerber finished the year by representing Germany in the Fed Cup final, where the team took on the Czech Republic. After dropping her first match to Lucie Šafářová, she came up against Petra Kvitová. There, Kerber dropped the first set tiebreak, and then avoided a bagel down 0–3 in the second set by coming back to win it 6–4. She came up short in the decider, however, as Kvitová launched her comeback from 1–4 down to win it 6–4, ensuring the Czech team an unassailable 3–0, and the title.

Kerber started her year of 2015 by posting deep runs in both Brisbane and Sydney International, with quarterfinal and semifinal results, respectively. However, at the Australian Open, she crashed out in the opening round to Irina-Camelia Begu, and it was the first time Kerber lost at the first hurdle of a Grand Slam tournament since Wimbledon in 2011. Representing Germany in the Fed Cup quarterfinals where the Germans faced Australia, Kerber scored a win out of her two matches played, over Samantha Stosur, but the 2014 runner-ups would progress by winning the tie 4–1. Her form however did not improve further across the months of February and March as she netted just two wins across five tournaments played, and by the start of April, she had fallen out of the top 10, for the first time since May 2012.

At the Charleston Open, fifth seed Kerber overcame a 4–2 third-set deficit to defeat Evgeniya Rodina in her opening match, and then cruised past Lara Arruabarrena to reach the last eight. Her run continued with a win over Begu in two tight sets, followed by another straight-set victory, over fellow German and defending champion Andrea Petkovic, to advance to her first final of 2015. There, Kerber faced seventh seed Madison Keys and she fought back from a 4–1 deficit in the third set to claim her fourth WTA title and her first since the fall of 2013, besides it being her first tournament triumph on clay. In the Fed Cup semifinals, where Germany faced Russia, Kerber won her only rubber played, against Anastasia Pavlyuchenkova in straight sets, dropping just one game. The win, however, was not enough as Germany lost the deciding doubles match.

Kerber was unseeded in Stuttgart to open her season on red clay, and defeated Alexa Glatch in straight sets, before upsetting three-time defending champion Maria Sharapova in three sets. In the quarterfinals, she saw off Ekaterina Makarova, before beating Madison Brengle to reach her second final of the year. There, she fought back from a set and 5–3 down to prevail over Caroline Wozniacki, thus scoring her fifth career title, also her first on home soil, which saw her extend her winning streak on clay to 11 matches. That streak, however, expired in the hands of Stosur in the opening round of Madrid. At the Italian Open, Kerber reached the second round after defeating Alizé Cornet but lost to Begu once more. After a semifinal run in Nuremberg, Kerber exited the French Open in the third round from a set up, in the hands of Garbiñe Muguruza.

On grass, Kerber had a bright start, by lifting the title at the Birmimgham Classic where she was the fourth seed. En route, she advanced to the quarterfinals after defeating Tsvetana Pironkova and Jelena Janković. She then beat Kateřina Siniaková in straight sets to set up an all-German semifinal where she faced Sabine Lisicki, their first meeting since Wimbledon in 2012. Kerber won in straight sets and subsequently advanced to her third final of the season where she defeated Karolina Plíšková in a tight three-setter for her sixth career title, her first on grass. This marked the first time Kerber had won more than two titles in a season. At the Wimbledon Championships, Kerber advanced to the third round where she crossed paths with Muguruza once more, and lost to the eventual runner-up in three sets.

Kicking off her US Open Series campaign in Stanford, fifth-seeded Kerber defended her runner-up result from a year ago by beating Daria Gavrilova and Ana Konjuh to make the last eight where she edged past second seed Agnieszka Radwańska in a three-set marathon to reach the last four. She then beat Elina Svitolina to make the final where she met Plíšková, and defeated the Czech in three sets once again, this time to lift her seventh career title, and became the only player to win titles across all surfaces in 2015. Kerber did not enjoy better results on American hard courts in her following tournaments with early losses in Toronto and Cincinnati. At the US Open, she was the 11th seed came up short in the third round again, this time in a three-set defeat to 20th seed and two-time runner-up Victoria Azarenka in an epic encounter.

Kerber bounced back with stronger results in the Asian swing, starting off with a quarterfinal showing in Tokyo where she lost to Wozniacki in three sets. At the Wuhan Open, Kerber reached the last eight after dispatching Jelena Janković and Camila Giorgi, before moving past Coco Vandeweghe via retirement. In the semifinals, she lost to Muguruza once again, this time in straight sets. At the China Open next, Kerber advanced to the last eight where she lost to Radwańska in straight sets. Kerber would then reach her fifth final of the year at the Hong Kong Open but finished runner-up for the first time this season, falling to Janković in three sets. It was announced on 21 October that Kerber had qualified for the WTA Finals, marking her third appearance here. As the sixth seed, she was drawn into the same group with Muguruza and fellow left-handed players Petra Kvitová and Lucie Šafářová. She exited in the round-robin stage, managing just one win that came over Petra Kvitová. Having spent patches of 2015 out of the top 10, Kerber eventually concluded the season as world No. 10, maintaining her season finish from 2014.

Kerber began the year at the Brisbane International, posting a runner-up result, with wins over Camila Giorgi, Madison Brengle, Anastasia Pavlyuchenkova and Carla Suárez Navarro en route to the final, where she lost to former champion Victoria Azarenka. In Sydney, Kerber defeated Elina Svitolina in the opening round but then withdrew with an illness.

Kerber was the seventh seed at the Australian Open and defeated Misaki Doi in the first round, having been a match point down. She then scored a triplet of straight-set wins over Alexandra Dulgheru, Brengle, and compatriot Annika Beck to reach her first quarterfinal in Melbourne, completing the sweep of quarterfinal appearances at all four Grand Slams in the process. In the quarterfinals, she avenged her Brisbane loss by defeating two-time champion Victoria Azarenka in straight sets, her first win against the Belarusian, to advance to the third Grand Slam semifinal of her career, her first since Wimbledon in 2012. There, Kerber defeated Grand Slam semifinal debutante Johanna Konta in straight sets to reach her maiden Grand Slam final. She defeated defending champion and world No. 1, Serena Williams, earning her first Grand Slam title and becoming the first German to do so since 1999. Besides becoming the first player to win a Grand Slam having been down match point in the first round, she also recorded her best ranking to date as world No. 2 following the achievement, surpassing her prior career-high of No. 5 set that she had set in 2012.

Representing Germany in the Fed Cup quarterfinals where the Germans faced the Swiss team, Kerber went 1–1 in her singles matches, with Germany losing the tie in the end. Kerber then endured a dry spell across the Qatar and Indian Wells Opens, dropping both her openers. However, she bounced back with a run to the semifinals in Miami where she was stopped by eventual champion Victoria Azarenka. At the Charleston Open, top seed and defending champion Kerber sailed into her consecutive semifinal but this time, retired to eventual champion Sloane Stephens due to a viral illness. In the Fed Cup World Group play-offs, the German team faced Romania and Kerber duly emerged victorious in her both her singles rubbers, over Irina-Camelia Begu and Simona Halep, losing only four games to the latter, and also her first ever win over her, to keep Germany in the World Group as the team would win the tie 4–1.

Kerber was the defending champion in Stuttgart, and successfully defended a title for the first time in her career. After a first-round bye, she beat Beck, Carla Suárez Navarro, and Petra Kvitová to reach the final. There she faced compatriot and qualifier Laura Siegemund and won ten games in a row from 2–4 down in the first set to defeat Siegemund and score her second title of the year and ninth of her career. Another losing streak ensued to close her clay season, however, which includes a loss to Kiki Bertens at the French Open, Bertens then becoming an eventual semifinalist herself.

Prior to Wimbledon, Kerber attempted to defend her title at the Birmingham Classic and sailed into the last eight where she met Suárez Navarro once again but lost to Spaniard. At Wimbledon, fourth-seeded Kerber did not drop a set, with wins over Laura Robson, Varvara Lepchenko, Carina Witthöft, Doi and fifth seed Halep, en route to her second semifinal here. There, she moved past former champion Venus Williams to reach the final, where she was defeated by Serena Williams, in a rematch of their Australian Open championship encounter earlier in the year, in straight sets.

After Wimbledon, Kerber played at the Swedish Open where she withdrew before her second round match due to an injury. She then reached her first quarterfinal at the Canadian Open with three-set wins over Mirjana Lučić-Baroni and Svitolina. She then beat Daria Kasatkina to make the last four when lost to eventual champion Halep. At the Rio Olympics, Kerber defeated Mariana Duque Mariño, Eugenie Bouchard, Samantha Stosur to record her second Olympic quarterfinal appearance. Two more wins, over Konta and Madison Keys, saw Kerber book her spot in the gold medal match, where she was defeated by surprise finalist Monica Puig of Puerto Rico in three sets. Kerber's strong summer continued at the Cincinnati Open where she had her first opportunity to dethrone Serena Williams as the world No. 1 but needs to win the title to do so. Kerber did make the final where she faced 15th seed Karolína Plíšková but lost in straight sets. Nevertheless, Kerber's strong results throughout the year thus far ensured herself qualification for the WTA Finals, which was announced on 22 August following the conclusion of the Cincinnati tournament.

At the US Open, Kerber beat the likes of Polona Hercog, Lučić-Baroni, CiCi Bellis and 14th seed Petra Kvitová to make the quarterfinals here for the first time since her semifinal run back in 2011. She continued with wins over eighth seed and 2015 runner-up Roberta Vinci, and a resurgent Caroline Wozniacki to reach her third Grand Slam final. Her win over Wozniacki, in the semifinals, combined with Serena Williams' defeat to 10th seed Plíšková in the same round meant that Kerber would unseat Serena Williams as the world No. 1 when the new rankings were released on 12 September the following week. In the championship match, Kerber gained her revenge over Plíšková by prevailing over the Czech in three sets to claim her second Grand Slam title, the 10th title overall of her career.

At the Wuhan Open, her first tournament since claiming the world No. 1 ranking, Kerber reached the third round where she fell short to Kvitová in a 3-hour-long match. She then fell in the same round at the China Open, this time to Svitolina. Her penultimate tournament appearance of 2016 came at the Hong Kong Open where she lost in the quarterfinals to Daria Gavrilova. On 17 October 2016, Serena Williams pulled out of the WTA Finals in Singapore due to a shoulder injury, and that withdrawal secured Kerber's spot at the summit of the WTA rankings for the rest of the year, including the year-end No. 1 ranking, another first in Kerber's career. As the top seed of the Tour Finals, Kerber was drawn in the same group alongside Halep, Keys, and Dominika Cibulková. She won all of her round robin matches, scoring back-to-back wins here for the first time in her career as well, en route to her first semifinal here. She then defeated defending champion Agnieszka Radwańska in straight sets to reach the final where she faced Cibulková once again that week, to whom she lost in straight sets.

At the start of the 2017 season, Kerber competed at the Brisbane International as the top seed, and won her opening match against Ashleigh Barty in three sets but then lost to Elina Svitolina in the quarterfinals. The following week in Sydney, she dropped opening match to Daria Kasatkina. As the top-seeded player and defending champion at the Australian Open, Kerber overcame a mid-match lapse to see off Lesia Tsurenko in the first round, where she squandered a match point in the second set. Kerber then defeated compatriot Carina Witthöft in the second round and Kristýna Plíšková in the third round. In the fourth round, Kerber lost to eventual semifinalist CoCo Vandeweghe in straight sets. Serena Williams, who lost to Kerber in the championship match here 12 months ago, won the tournament this time and amassed enough points to take back the top ranking from Kerber.

After a winless showing in Doha, Kerber made the last four in Dubai where she lost to eventual champion Svitolina. The following month, in Indian Wells, Kerber reached the round of 16 where she lost to another eventual champion, this time in Elena Vesnina, but it was enough for Kerber to regain the world No. 1 ranking owing to Serena Williams' withdrawal from the event. This was then followed by a quarterfinal appearance in Miami where she lost to Venus Williams, and then a runner-up showing in Monterrey, where in a rematch of the 2013 final, Kerber fell short to Anastasia Pavlyuchenkova in three sets.

Kerber's season on clay began with her ranking at world No. 2, and a loss in her opener in Stuttgart to eventual runner-up Kristina Mladenovic. At the Madrid Open, Kerber won back-to-back wins to reach the third round where she retired against Eugenie Bouchard with a back issue, but returned to world No. 1 after the tournament's conclusion nevertheless. At the French Open, Kerber became the first female top seed in history to be ousted in the first round here, falling in straight sets to Ekaterina Makarova. However, she fared better as the season moved to grass courts, by making the quarterfinals in Eastbourne where she was defeated by Johanna Konta. At Wimbledon, Kerber made the second week, falling in the round of 16 to the eventual champion Garbiñe Muguruza in three sets. Due to Kerber's early exit and Simona Halep's loss to Konta in the quarterfinals, Karolína Plíšková became the new No. 1 after the tournament.

Across the US Open Series, Kerber's struggles in 2017 continued as she netted just one victory across three tournament appearances in the North American hard court summer, which includes a first-round loss to Naomi Osaka at the US Open, where she was the defending champion. With this loss Kerber dropped out of the top 10. The following month, at the Pan Pacific Open, Kerber recorded her best result since Monterrey back in April, as she took revenge on Osaka and then defeated Kasatkina and Plíšková, before falling in the last four to Pavlyuchenkova. The said win over Plíšková in Tokyo was Kerber's best win by ranking since the 2016 WTA Finals. She would go on to score just one more win for the rest of the year, however, in the first round of the China Open where she beat Osaka once again. After dropping both her two matches in the group stage at WTA Elite Trophy, to Pavlyuchenkova and Barty, Kerber dropped out of top 20 for the first time since 2012, and finished the year ranked world No. 21. Shortly after, on 16 November 2017, Kerber announced that she had parted ways with longtime coach Torben Beltz and has hired Wim Fissette as new coach.

Kerber started her 2018 season with a first ever appearance at the Hopman Cup, where she partnered with Alexander Zverev. She went undefeated in her singles matches and helped the team cruise into the final where they lost to Switzerland. Kerber followed up that performance with her first title in more than a year, at the Sydney International next. To make the final, she edged past Lucie Šafářová and Venus Williams, saving a match point against the former, to make the quarterfinals where she beat Dominika Cibulková. She set up a championship match with home star Ashleigh Barty after moving past Camila Giorgi. There, she beat the Aussie in straight sets for her 11th career title. At the Australian Open, 21st-seeded Kerber moved into the fourth round with wins over Anna-Lena Friedsam, Donna Vekić and former world No. 1 Maria Sharapova, all in straight sets and dropping no more than four games a set. There, she saw off Hsieh Su-wei in three sets to move into her second quarterfinal here, where she swept aside Madison Keys. In the semifinal, a clash against world No. 1, Simona Halep, both had two match points in the third set but neither were converted. The match then ended 9–7 in the third set, with Halep prevailing.
