Cork City U19

The current club are not the first to use the name Cork City. During the 1920s, teams referred to as Cork City competed in both the Munster Senior League and the Munster Senior Cup. A team named Cork City finished as Munster Senior Cup runners up in 1924–1925. Another Cork City F.C. also played in the League of Ireland between 1938 and 1940.

Following the bankruptcy of Cork United in 1982, senior football returned to the city with the formation of a new Cork City FC in 1984. Founded by officials from several Cork clubs (including Cork United and Avondale United), the new club was elected to the League of Ireland. Bobby Tambling was the first manager appointed to the club, but he was replaced by Tony 'Tucker' Allen after only 13 games.

In its first and second seasons, the young club barely averted relegation to the new First Division – failing to win a single game at home in Flower Lodge and avoiding relegation only on goal difference. The club reached the semi-finals of the FAI Cup, but were knocked-out by Shamrock Rovers – in the last match played at the Lodge.

In 1986, the club moved to a new home at Turners Cross, where new manager Noel O'Mahony brought Cork to a midtable finish. The following year, former Ireland striker Eamon O'Keefe arrived as manager, delivering the Munster Senior Cup, and the League of Ireland Cup (the club's first national silverware).

By 1988, O'Mahony was re-installed as manager, and the side finished eighth in the league, and a loss to champions Derry City in the FAI Cup final earned the club its first European ticket. While Torpedo Moscow knocked the club out of the 1989–90 European Cup Winners' Cup, City earned a fifth-place finish in the Premier Division, and the Munster Senior Cup was reclaimed.

The early 1990s saw lengthy unbeaten league runs, high league positions, retention of the Munster Senior Cup through four years, and a number of games in European competition. The most notable European game was a UEFA Cup tie with Bayern Munich, which saw City hold the Germans 1:1 at Musgrave Park before falling 0:2 to late goals in Bavaria. 1993 saw Cork City land the League of Ireland Premier Division title for the first time, after a complicated three team play-off. O'Mahoney resigned and the club moved to a new stadium in Bishopstown at the end of the season.

Damien Richardson took the helm and the 1993/94 season began with City coming from three goals down to beat Welsh side Cwmbran Town in the UEFA Champions League. In the following round, they suffered odd-goal defeats both home and away to Turkish side Galatasaray. City finished in runners-up position in the league that year.

1994/95 was a varied season for Cork City. After a strong start to the season, financial pressures forced Richardson to resign and with Bishopstown not being developed to plan, games were switched to Cobh, Turners Cross, and an enforced trip to Tolka Park. Noel O'Mahony was re-appointed as manager but the title challenge collapsed. The club did have successes in the Munster Senior Cup and League of Ireland Cup that season however.

At the start of the 1995/96 season Rob Hindmarch took the reins, but the club was in trouble. With the stadium dragging it under, the receiver was called in and the club left 'homeless'. Efforts to save the situation saw a new board installed and a move back to Turners Cross. With limited funds, Hindmarch had skimmed along but relegation still threatened, and an FAI Cup exit saw Dave Barry appointed. The team managed a ninth-place finish in the league, and for the first time in five years City lost the Munster Cup – to Waterford junior side Waterford Crystal.

1996/97 saw City finish in fourth place. The club also narrowly lost out in the League Cup with an unexpected loss to First Division Galway United. Crowds began to increase, and the Munster Senior Cup was recaptured. The following season, Cork performed well in the InterToto Cup and the team improved to third in the league. Dave Barry's reign reached its high point in that year, when City won the 1998 FAI Cup. Cork began the following season with eight straight wins but in the end had to settle for second place, as three defeats to champions St Patrick's Athletic were costly. After finishing runner-up for the second season in a row in 1999/2000, Barry resigned to be replaced by Colin Murphy.

Colin Murphy stayed for one FAI Super Cup game before departing to Leicester City just days before a UEFA Cup game. His replacement, Derek Mountfield, lasted less than a season and was replaced by former player Liam Murphy. Under Murphy, City embarked on a 13-game unbeaten run that brought an Intertoto ticket and a tenth Munster Cup success.

In 2001, a controversial link-up was proposed between City, English side Leicester City and local outfit Mayfield United. Fans protested however, and the link-up never materialised. Also in 2001, the board of directors stepped down and businessman Brian Lennox assumed control and lead the club to a professional era.

2002 was most notable as a time of transition, as several older players, who had been a mainstay of the team in the 1990s, left the club or joined the coach staff. They were replaced by younger signings – such as George O'Callaghan, John O'Flynn and Dan Murray.

In February 2003, ex-St. Pat's manager Pat Dolan was unveiled as the new boss and he led City to third place in the new summer season. Dolan's second season as manager also proved successful, as City surpassed Malmö FF and NEC Nijmegen in the Intertoto Cup and secured second place in the league.

Dolan was controversially sacked in pre-season 2005 and replaced by former manager Damien Richardson. In 2005, Richardson lead Cork City to their second league championship – winning on the final day of the season with a 2–0 victory over Derry City. In the same year, Cork City finished runners-up the FAI Cup.

2006 saw further upgrade work begin at Turners Cross and City met Apollon Limassol and Red Star Belgrade in the UEFA Champions League. The club lost to Drogheda United in the Setanta Cup Final, finished 4th in the league, and secured a place in the Intertoto and Setanta Cup.

At the start of the 2007 season, two new signings were deemed ineligible for play. This mirrored an inconsistent season start, with elimination from the Setanta Cup, a home win against St. Pat's and a record-equaling 4–1 defeat to Sligo Rovers. In August 2007, Roy O'Donovan left for Sunderland for a record LOI fee of €500,000. 2007 also saw the club's ownership change hands: from chairman Brian Lennox to venture capital firm "Arkaga". Despite an FAI Cup win, manager Damien Richardson's future at the club was in doubt, and – after some acrimony – he and the club parted ways.

In January 2008, former Longford Town boss Alan Mathews became manager, and the club signed several players – including taking advantage of FIFA's changes to the "3 club" rule by re-signing George O'Callaghan from Ipswich Town. However O'Callaghan was later dropped and released. City were knocked out of the first qualifying round in European competition by FC Haka. While David Mooney retained the league's top scorer spot, City failed to take points from Bohemians or St. Pats and finished fifth in the league. The club did however gain some silverware, beating Glentoran in the Setanta Sports Cup final. Off the pitch the club suffered a considerable threat when, in August 2008, after investment difficulties with venture capital firm Arkaga, the club entered into examinership. With debts of up to €800,000, cost-cutting measures were implemented. Under related rules, the club was docked 10 points in the league. In October 2008 the High Court ruled in favour of Tom Coughlan's bid to take over the club, and ended the examinership.

Paul Doolin replaced Mathews as manager for the 2009 season, and the side gained a number of positive results early in 2009 – including defeating Roy Keane's touring Ipswich Town 2–0. Despite these on pitch results however, the club's future was left in considerable doubt following a High Court decision on outstanding Revenue receipts. A "winding up" order was issued when no agreement could be reached on tax payments. The club were given several extensions to pay or to appeal, and the club narrowly staved off closure by meeting a final deadline. Doolin left at the end of 2009, after leading the club to a third-place finish in the 2009 League of Ireland Premier Division.

Fallout from the financial and management difficulties in 2008 and 2009 followed the club into the new decade. Roddy Collins was appointed manager before the start of the 2010 season, despite questions over his contract status at Floriana F.C. Mounting pressure on owner Tom Coughlan (including threatened boycotts and censure by the FAI) resulted in his resignation as chairman. Club participation in the Premier Division was also left in doubt as licensing decisions were deferred pending changes in club ownership and payment of outstanding tax receipts.

Despite some temporary stays, and several months of court and legal wrangling, the club ultimately failed to gain a licence, meaning a deal on new ownership could not be secured, and the courts enforced a winding-up order on Cork City Investment FC Limited. Cork City fans entered the 2010 League of Ireland First Division with a new company under the name Cork City FORAS Co-op in the immediate aftermath of the winding up of the holding company CCIFC Ltd. The name of the club was restored on 1 June 2010 when a supporters' trust, FORAS, completed the purchase of the rights from Cork City Investments FC Ltd's liquidator. The team continued to compete in the League of Ireland as Cork City FORAS Co-op for the remainder of the season – though the club and most Irish media returned to calling the club Cork City FC, and supporters used this name during the entire period regardless.

Tommy Dunne (formerly assistant manager to Paul Doolin) was appointed first team manager, and oversaw the 2010 season. A number of players were called-up and played for the Ireland U23s, and others to the Ireland U21s. Shane Duggan, and Graham Cummins were both named in the PFAI First Division Team of the Year, while Cummins won the PFAI First Division Player of the Year award and was joint top-scorer in the First Division with 18 league goals. Cork ultimately finished sixth in the First Division in 2010.

In 2011, the club won the First Division, on the last day of the season, securing promotion to the Premier Division. The team also reached the league cup final, which was won by Derry City. The club were knocked-out of the 2012 FAI Cup by Shamrock Rovers in the third round, and finished sixth in the 2012 Premier Division league competition.

Results at the start of the 2013 season led to the removal of Tommy Dunne as manager by August, with Stuart Ashton overseeing the remainder of the season and a sixth-place finish. Former veteran player and record scorer John Caulfield was appointed manager in 2014, and oversaw unbeaten runs at the start and end of the season – keeping pressure on league-leaders Dundalk. However, despite pushing the title to a final day decider, Caulfield's side failed to pick up points from Dundalk and finished second in the 2014 Premier Division competition. The club were also runners-up in the 2015 season, again finishing second to Dundalk. This won them a place in the qualifying rounds of the UEFA Europa League, where they made it to the third round, their best European record since 1997. For the third consecutive year, Cork City finished second to Dundalk in the 2016 Premier Division. However, in November they beat Dundalk in the 2016 FAI Cup final after Sean Maguire scored a last minute extra time goal to win Caulfield his first major trophy as manager.

The 2017 season started with a 22-game unbeaten run, however a number of less favourable results mid-season (and the departure of league top-scorer Sean Maguire to the UK and international duty) pushed City's "inevitable" championship win until later in the season. Cork City were named 2017 League of Ireland Premier Division champions on 17 October 2017 - with several games in hand. The club completed its first league and cup 'double', by winning the 2017 FAI Cup Final a few weeks later on 5 November 2017.

City started 2018 with a third successive President's Cup final win over Dundalk - in a game overshadowed by the death of former player Liam Miller, who died earlier in February 2018. As with the preceding four seasons, Dundalk were Cork's main rivals in the 2018 League of Ireland Premier Division and 2018 FAI Cup, with Dundalk ultimately winning both.

A series of poor results at the start of the 2019 season, saw the departure of John Caulfield as manager. Neale Fenn was appointed as Caulfield's replacement in August 2019, following a period where Frank Kelleher and John Cotter held interim management and coaching positions. Cork City finished the 2019 season in 8th position, with just 9 wins and 37 points.

With five games remaining in the 2020 season, and the club at the bottom of the table with just 2 wins, Neale Fenn was replaced as manager by Colin Healy. The club's relegation to the League of Ireland First Division was sealed on 24 October 2020, as their bottom of the table 10th-place finish was confirmed following a Finn Harps win over Bohemians.

In late October 2020, the supporters' trust agreed to sell the club to Preston North End owner Trevor Hemmings through his company Grovemoor Limited. However, in mid-December 2020, it was reported that the proposed sale would not progress, as Grovemoor Limited could not agree "terms on a lease agreement with the Munster Football Association" for the use of Turner's Cross. Hemmings, who had previously "rescue[d] Cork City" by increasing the payments offered for several player sell-on clauses, died in 2021. Relegated to the first division for the 2021 season, the club finished in sixth place, outside the premier division promotion places.

After winning the 2022 LOI First Division title in October 2022, with "two games to spare", the club secured promotion back to the premier division for the subsequent season. In late 2022, FORAS voted to transfer ownership of the club to businessman Dermot Usher, via a new company (Cathair Chorcaí 2022 FC Limited), subject to the execution of "deeds of surrender" on the call-option agreed with Grovemoor Limited in 2020. Liam Buckley was appointed as sporting director in early May 2023, and Colin Healy resigned as first team manager shortly afterwards. In September 2023, Richie Holland was named manager. In November 2023, after finishing ninth and losing to an extra-time penalty in the 2023 playoff decider, Cork City were again relegated to the LOI First Division for the 2024 season.

Tim Clancy replaced Richie Holland as coach towards the end of 2023, and was first team manager at the start of the 2024 season. A "youthful" and "experiment[al]" Cork City side were knocked out of the 2023-2024 Munster Senior Cup by Wilton United at the last-16 stage. The club started the 2024 League of Ireland First Division season with a 17-game unbeaten run. In August 2024, with the club "closing on an immediate return" to the Premier Division, Cork City re-signed former players Ruairí Keating (released from St Patrick's Athletic) and Sean Maguire (released from Carlisle United). With six games to spare and after a 12-game unbeaten run, Cork City secured the First Division title and automatic promotion after a win against UCD in early September 2024.
