The 2011 Football League Cup final was the final match of the 2010–11 Football League Cup, the 51st season of the Football League Cup, a football competition for the 92 teams in the Premier League and the Football League. The match was contested by Arsenal and Birmingham City, at Wembley Stadium in London, on 27 February 2011. Birmingham City won the game 2–1 and were guaranteed a spot in the third qualifying round of the 2011–12 UEFA Europa League. Mike Dean was the referee.

Arsenal held the advantage over Birmingham in the league matches between the two sides in 2010–11, having beaten them 2–1 at the Emirates Stadium in October and again 3–0 at St Andrew's on New Year's Day.

Arsenal had played in six Football League Cup finals, but had only won two, most recently in 1993 when they beat Sheffield Wednesday 2–1. Birmingham's only League Cup title came in 1963, when they beat local rivals Aston Villa 3–1 on aggregate after a two-legged final. They also reached the 2001 final, which was played at the Millennium Stadium in Cardiff against Liverpool, but the 2011 final was Birmingham's first appearance in the final of a major competition at Wembley for nearly 55 years, their last being the 1956 FA Cup final.

In the build-up to the game, Arsène Wenger criticised the FA and UEFA for overpricing tickets for their finals. ^{[citation needed]}

A number of Arsenal players missed out on the final. Thomas Vermaelen was not fit, while goalkeeper Łukasz Fabiański had been ruled out for the rest of the season. Theo Walcott picked up a sprained ankle in a match against Stoke City a few days prior, and captain Cesc Fàbregas was also injured in that game; both missed the final. Abou Diaby was also injured.

For Birmingham, Scott Dann was ruled out for the rest of the season following an injury in the League Cup semi-final, while James McFadden was still not recovered from an injury received in September. Former Arsenal player Alexander Hleb was injured in an FA Cup match the week before, and failed to recover in time to play. David Bentley, who had replaced Hleb in that match, was cup-tied, having played for Tottenham Hotspur in their defeat to Arsenal in the third round.

Arsenal were rated heavy odds-on favourites for the match, with Birmingham rated at worse than 5/1 against to win the game in 90 minutes.

There was a moment of contention just two minutes into the match as an early Birmingham chance was created through Lee Bowyer, who appeared to be fouled by Arsenal goalkeeper Wojciech Szczęsny in what would probably have been a penalty kick and red card for the keeper. However, Bowyer had already been flagged offside (a decision that replays proved was incorrect).
