Sheffield Wednesday Football Club is a professional association football club based in Sheffield, South Yorkshire, England. The team will compete in League One, the third tier of the English football league system, in the 2021–22 season after finishing 24th in the 2020–21 Championship. Formed in 1867 as an offshoot of The Wednesday Cricket Club (itself formed in 1820), they went by the name of the Wednesday Football Club until changing to their current name in 1929.
Wednesday is one of the oldest football clubs in the world of any code, and the third-oldest professional association football club in England. In 1868 its team won the Cromwell Cup, only the second tournament of its kind. They were founding members and inaugural champions of the Football Alliance in 1889, before joining The Football League three years later. In 1992, they became founder members of the Premier League. The team has spent most of its league history in English football's top flight, but they have not played at that level since being relegated in 2000.
The Owls, as they are nicknamed, have won four league titles, three FA Cups, one League Cup and one FA Community Shield. Wednesday have also competed in UEFA cup competitions on four occasions, reaching the quarter-finals of the Inter-Cities Fairs Cup in 1963. In 1991, they defeated Manchester United 1–0 in the Football League Cup Final as a tier 2 team. As of 2019 they remain the last team to win one of English football's major trophies while outside the top flight
In the 19th century, they played their matches at several stadiums around central Sheffield, including Olive Grove and Bramall Lane. Since 1899, the club has played all its home matches at Hillsborough stadium, a near-40,000 capacity stadium in the north-west Sheffield suburb of Owlerton. Wednesday's biggest rivals are Sheffield United, with whom they contest the Steel City derby.
