The EFL League One play-offs are a series of play-off matches contested by the association football teams finishing from third to sixth in the EFL League One table and are part of the English Football League play-offs. As of 2022[update], the play-offs comprise two semi-finals, where the team finishing third plays the team finishing sixth, and the team finishing fourth plays the team finishing fifth, each conducted as a two-legged tie. The winners of the semi-finals progress to the final which is contested at Wembley Stadium.
For the first three years, the play-off final took place over two legs, played at both side's grounds. Swindon Town won the first Third Division play-off final in 1987, requiring a replay to defeat Gillingham. From 1990, the play-off final was a one-off match, hosted at the original Wembley Stadium, while from 2001 to 2006, the final was played at the Millennium Stadium in Cardiff as Wembley was being rebuilt. Since 2007, the match has been hosted at Wembley Stadium except for the 2011 final which took place at Old Trafford to avoid a clash with the 2011 UEFA Champions League final.
When the third tier play-offs were first contested in 1987, they were known as the Football League Third Division play-offs. From 1993 to 2004, following the creation of the FA Premier League as a breakaway from the Football League, the competition became known as the Second Division play-offs, and since 2005 has taken its current name as the League One play-offs following a rebranding of the remaining three divisions of the Football League.
