Minnesota United

In January 2010, the National Sports Center announced they would field a new team to replace the Minnesota Thunder. The Thunder at the time were not officially folded but were facing financial ruin. Following a team-naming contest, the National Sports Center (NSC) announced the official team name would be NSC Minnesota, with the team nickname being Stars on February 5, 2010. Five days later, former USMNT player Manny Lagos was named as the club's first head coach.^[] The team played its first official game on April 11, 2010, a 2–0 loss to the Vancouver Whitecaps. The first goal in franchise history was scored by Daniel Wasson in their next game, a 1–0 victory over the Carolina RailHawks.

On January 9, 2012, the club announced a new logo as well as a new name. The NSC portion of the name, which had led to confusion, was dropped, with the new name being the Minnesota Stars FC. The new logo was revealed with the word 'NSC' removed and the state motto, L’Étoile du Nord, added. The team continued a search for a new owner in the offseason and opened the 2012 season with a 0–0 draw against the Carolina RailHawks at the Metrodome in front of a crowd of 8,693.

On March 25, 2015, Major League Soccer commissioner Don Garber announced Minnesota United as the league's 23rd club and awarded the franchise to a group led by McGuire. The ownership group includes other Minneapolis-St. Paul sports owners: Jim Pohlad, owner of the MLB's Minnesota Twins; Glen Taylor, former owner of the NBA's Minnesota Timberwolves; and the late Glen Nelson, former investor of the NHL's Minnesota Wild, along with his daughter Wendy Carlson Nelson, who is a board member of the Carlson Hospitality Company. They beat out a competing bid by Minnesota Vikings owners Mark and Zygi Wilf (both of whom would later become minority owners of MLS expansion franchise Nashville SC). Garber said Minnesota would begin play in 2017 or 2018 – if Los Angeles FC was not ready to play in 2017, Minnesota would take its place.

The Twin Cities were previously represented by the Minnesota Kicks in the top-level North American Soccer League (NASL) from 1976 to 1981, and later the Minnesota Strikers in 1984. The Kicks played their home games at Bloomington's Metropolitan Stadium, while the Strikers played at the Hubert H. Humphrey Metrodome.

The Minnesota Legislature had passed a bill in May 2012 for a new NFL stadium projected to open by fall 2016 and gave a provision allowing for the Vikings to pursue an MLS franchise, including a five-year exclusive window to host MLS games in the new stadium. The Wilfs' bid also had the support of Minneapolis Mayor Betsy Hodges, and Minnesota Senator Tom Bakk called Major League Soccer to inform them that the state legislature would not be providing financing for a soccer-specific stadium. However, Commissioner Garber said that whenever possible, the league preferred a stadium that would be an "outdoor, soccer-specific stadium, 20,000 seats, playing on grass" as opposed to larger, covered venues with artificial turf like U.S. Bank Stadium, and McGuire had the support of Hennepin County Commissioner Mike Opat and at least three members of the Minneapolis City Council.

The team played their inaugural Major League Soccer match on March 3, 2017, a 5–1 away defeat to the Portland Timbers at Providence Park. The result represented the heaviest defeat by an expansion side making their debut. Previously no MLS expansion team had lost by more than two goals in their first game. Christian Ramirez scored the team's first MLS goal. The following weekend they played their home opener against fellow expansion team Atlanta United FC in a snowstorm with an MLS record-low kickoff temperature of 19 °F (−7 °C). They lost the game 6–1, handing Minnesota more unwanted records including the record defeat of any expansion side and becoming the only team in MLS history to concede five or more in consecutive games. Following a 2–2 draw at the Colorado Rapids and a 5–2 loss at New England Revolution, United had conceded 18 goals in their first four games, which is an MLS record through the first six games of a season. The team got its first win in MLS with a 4–2 home victory over Real Salt Lake on April 1. As the season progressed, so had the team. In the mid-season, Minnesota had acquired Duluth native Ethan Finlay from Columbus Crew SC and made other signings to improve on the field. United finished its inaugural MLS season in ninth place in the Western Conference.

MNUFC lost two key players - midfielders Kevin Molino and Ethan Finlay - to season-ending knee injuries early in the 2018 season. Shortly before Finlay's injury, the team signed its first Designated Player; Darwin Quintero joined Minnesota United from Liga MX's Club América. Despite joining the team after five matches had already been played, Quintero led the team for 2018 in both goals (11) and assists (15). On July 4, 2018, Quintero scored a hat trick in a home match versus Toronto FC, the first in Minnesota United's history. Colombian forward Ángelo Rodríguez joined the club as its second Designated Player later in the season. MNUFC averaged nearly 24,000 fans per match during its second year at TCF Bank Stadium, including a crowd of 52,242 at the final match in their temporary home. The team managed 10 wins at home, but struggled on the road with only one victory.

MNUFC made substantial roster additions prior to the 2019 season, including its third Designated Player, midfielder Ján Greguš from F.C. Copenhagen; 2017 MLS Defender of the Year Ike Opara, traded from Sporting KC; longtime Seattle Sounders FC defensive midfielder Osvaldo Alonso; Ligue 2 defender Romain Métanire; and goalkeeper Vito Mannone, loaned from Reading F.C.

After beginning the 2019 season with five matches on the road, MNUFC played their first match at the new Allianz Field on April 13, earning a 3–3 draw versus New York City FC. The team went on to post 10 wins, 6 draws and 2 losses at home. MNUFC's performance on the road was vastly improved in 2019, posting 5 wins and 2 draws including a 2-0 statement win at LAFC on September 1.

The club made a very successful run in the 2019 U.S. Open Cup. On August 27, the club traveled to Mercedes Benz Stadium to take on Atlanta United in the Cup final, Minnesota's first final appearance since joining MLS. The match resulted in a 2–1 Atlanta victory.

MNUFC finished fourth in the Western Conference, after placing as high as second late in the regular season. As a result, the club was awarded a spot in the 2020 Leagues Cup. MNUFC played in its first MLS playoff match, hosting the LA Galaxy on October 20; the result was a 2–1 defeat.

Two players received league-wide honors at the conclusion of the season. Ike Opara was named 2019 MLS Defender of the Year, winning the award for the second time. Vito Mannone, who earned 11 cleansheets and conceded only 43 goals, was named 2019 MLS Goalkeeper of the Year.

After the 2019 season, Minnesota United traded Darwin Quintero to the Houston Dynamo for midfielder Marlon Hairston and $600,000 in allocation money. Upon the end of goalkeeper Vito Mannone's loan, Minnesota United brought in Tyler Miller (soccer) via trade with Los Angeles FC to take the starting job. Prior to the season, MNUFC added a number of players including striker Luis Amarilla via loan from Club Atlético Vélez Sarsfield.

The Loons got off to an excellent start for 2020 with two convincing road wins at the Portland Timbers and San Jose Earthquakes in March, before Major League Soccer suspended its season due to the COVID-19 epidemic, first for 30 days and then indefinitely as the severity of the epidemic became clearer.

The 2020 season restarted in July with the league's MLS is Back Tournament, held in Orlando, Florida and including 24 of the league's 26 teams. The month-long tournament included a group stage, counted as part of the regular season standings; and a knockout stage. The Loons finished second in Group D, with one win and two draws. In the knockout stage, MNUFC defeated the Columbus Crew 1–1 on penalty kicks and the San Jose Earthquakes 4–1, before losing to Orlando City SC in the tournament semifinal.

Following the tournament, the 2020 season resumed normal match play, with a planned schedule of 18 matches ending on November 8. The Loons continued to add players, with midfielder Emanuel Reynoso joining the club from Boca Juniors as a Designated Player, and veteran forward Kei Kamara joining via trade from the Colorado Rapids.

MNUFC finished the regular season in fourth place in the MLS Western Conference. They hosted their second playoff match in franchise history, defeating the Colorado Rapids 3–0 at Allianz Field, then went on to defeat No. 1 seeded Sporting Kansas City 3–0 on the road. The Loons then traveled to Seattle for the Western Conference final match against the Sounders. Despite leading 2-0 at the 75th minute, Seattle scored three straight late goals, including the winner in stoppage time to end Minnesota's historic run.

Although they had been minutes from advancing to the MLS Cup final in 2020, the 2021 season got off to a disappointing start, with four straight losses. In mid May, the Loons began to quickly climb from the bottom of the table, losing only two of their next seventeen games. Key players returned from injury and the squad signed Argentinian Franco Fragapane and Frenchman Adrien Hunou. They ended the regular season in fifth place, earning an opening round playoff berth on the road against the Portland Timbers, but their season was ended with a 3-1 Portland victory.

2022 saw the breakout of goalkeeper Dayne St. Clair who anchored an impressive 8-save shutout against the New York Red Bulls in his week 3 debut. Success started early for the Loons in July in 2022, with a 4-0 win in a friendly vs Premier League side Everton. The Loons had a solid first half of the season going 8-6-3 in the first 17 games. In the 2022 U.S. Open Cup Minnesota fell to USL League One side Union Omaha 2-1 in a notable upset. Midfield DP Emanuel Reynoso joined St. Clair in the 2022 MLS All-Star Game which was hosted at Allianz Field.

The second half of the season saw Minnesota struggle to find their footing with a 6-game winless streak going into the final 2 games of the season. Minnesota finally won a make-or-break game against Vancouver Whitecaps FC decision day to clinch the 6th seed in the 2022 MLS Cup playoffs, making them the only team in the western conference to qualify for the playoffs 4 years in a row. After finishing 120 minutes tied 1-1, MNUFC was knocked out of the playoffs in a (5)–(4) shootout against FC Dallas.
