Formation and early years The club was founded in 1912 as
Abbey United, named after the Abbey district of Cambridge. A club called Cambridge United existed in Cambridge from 1909, but it was not linked to the club that exists today. The club played in local amateur leagues for many of its early years, moving from ground to ground around Cambridge (see
Stadium below) before settling at the
Abbey Stadium. In 1949 the club turned professional, and changed its name to Cambridge United in 1951. Three years later, Cambridge United reached the Premier Division of the Southern League. which was surpassed by
Derby County in 2008) was followed by a further relegation in
1984–85 (equalling the then league record for most losses in a season, 33). These successive relegations, which also had a negative effect on the club's attendances as well as its finances, placed Cambridge United back in the
Fourth Division, the lowest professional league in
English football at the time. They had to apply for re-election in their first season back in the Fourth Division, and promotion would not be achieved for another four years.
Dion Dublin scored the only goal in a game against Chesterfield. Under Beck, United gained promotion from the
Fourth Division and had already reached the
FA Cup quarter finals in 1990, and reached them again a year later, and winning the
Third Division in 1991. The following season the club sacked John Beck and were relegated from the new
First Division. In 2005, after 35 years in the Football League, Cambridge United were relegated into the
Football Conference. This brought with it financial difficulties and the club filed for
administration on 29 April. On 22 July 2005 the club came out of administration with a deal being struck with
HM Revenue and Customs at the eleventh hour after the intervention of then sports minister
Richard Caborn. Cambridge had sold their Abbey Stadium home earlier in the season for £1.9 million to keep the club afloat.
In the Conference: 2005–2014 On the eve of the
2006–07 season, it was announced that former
Norwich City striker
Lee Power would be the club's new chairman taking over from Brian Attmore's caretaking reign.
Johnny Hon was also to rejoin the board as vice-chairman after
John Howard's resignation on conflict of interests grounds (owing to his ownership of Bideawhile 445 Ltd, United's landlords).
Jimmy Quinn was appointed manager soon after Power took charge and, after a difficult settling-in period which included a humiliating 5–0 loss to local rivals
Histon, he guided Cambridge United away from another possible relegation by achieving five wins from their last seven games of the season. After signing several respected and experienced players at the
non-league level in the following close season Quinn led Cambridge to their then longest ever unbeaten start to a season (
2007–08), which stretched to twelve games. Off the field, United reported several major sponsorship deals which seemed to point towards increased financial security. Halfway through the season the chairman, Lee Power, resigned. He was replaced by Wayne Purser. United finished the season in 2nd place, qualifying for the play-offs. They beat
Burton Albion in the semi-final, 4–3 on aggregate, but lost 1–0 to
Exeter City in the
final, played at
Wembley Stadium. Following the play-off defeat many players left the club, culminating in the departure of manager Jimmy Quinn. Quinn was succeeded by former
Southport manager
Gary Brabin, who appointed
Paul Carden as player-assistant manager. United finished the
2008–09 season again 2nd in the league, and also again reached the
play-off final, overturning a 3–1 deficit to beat
Stevenage Borough 4–3 on aggregate in the semi-final; however, they were beaten again at
Wembley Stadium, 2–0 by
Torquay United. Brabin was named as the Conference's Manager of the Season, but was sacked in the close-season after reportedly falling out with the chairman. He was replaced by
Martin Ling, who resigned just eight days into the job, before the start of the
2009–10 season and was followed days later by chairman George Rolls. The new board re-appointed Ling as manager the following week. Cambridge finished Ling's first season in 10th place – not enough for a playoff place. The following season, on 6 January 2011, with Cambridge in a similar position to where they finished the previous season, the club's owners put the club up for sale citing the need for new funds to take the club forward. Despite interest being expressed from a number of parties, no new owner has yet been found. Later the same month, the club's landlords
Grosvenor Group revealed the plans for a new community stadium, including potential new locations both within the city and outside it. At the start of 2011 Martin Ling was removed from his position as manager and replaced on a temporary basis by
CRC manager
Jez George. He managed to steer the club towards safety, finishing 17th, which led to George's role being made permanent. After having rebuilt the squad with players from the club's youth system and with astute signings in
Harrison Dunk and
Tom Shaw, George managed to lead Cambridge to a 9th-place finish, a huge improvement on their previous season. As well as the league, Jez George also took Cambridge to the quarter-final of the
FA Trophy (which was the furthest they had reached at the time), but lost 2–1 at home to minnows,
Wealdstone. Eleven games into the following season Jez George became Director of Football, and
Richard Money was announced as the new head coach of the club. The club spent much of the season in mid-table, finishing in 14th position with 59 points. The squad was greatly revamped, and United started
2013–14 with a record-breaking 16 games unbeaten. Cambridge finished the season in second place, qualifying for the play-offs. After beating
FC Halifax Town 2–1, on aggregate, in the semi-final, they won 2–1 against
Gateshead in the
final, held at
Wembley Stadium, gaining promotion back to the
Football League after a nine-year absence. The club also reached their first
FA Trophy final, held at
Wembley Stadium, where they beat
Gosport Borough 4–0.
2014–present: Back in The Football League In their first season back in the Football League, Cambridge United progressed to the fourth round of the
FA Cup, where they drew at home with
Premier League team
Manchester United. The match at the Abbey Stadium ended in a goalless draw, forcing a replay at
Old Trafford, which Manchester United won 3–0. In the league, Cambridge finished 19th with 51 points, 10 points above the relegation zone. The following
season started poorly, and Richard Money was sacked in November 2015, to be replaced by
Shaun Derry who would lead Cambridge to a 9th-place finish. In the
2019–20 season,
Mark Bonner was placed in temporary charge until the end of the season. Under Bonner, Cambridge won four from their final seven matches before the disruption caused by the
COVID-19 pandemic forced the cancellation of the season with Cambridge placed in 16th after a
points per game ruling. After being given the role permanently, Bonner guided Cambridge to promotion as runners-up in the
2020–21 season. Following additional investment from the club's co-owners, United bought back the Abbey Stadium from Grosvenor in September 2022, 20 years after selling it. In the
2022–23 season, United avoided relegation on the final day of the season after beating
Forest Green Rovers 2–0 at home on the final day of the season. They were relegated to League Two at the end of the
2024–25 season after finishing 23rd. ==Colours and badge==
