2012–13 Yeovil Town F.C. season

The 2012–13 season was the 10th season in the Football League and the 8th consecutive season at the third tier of English football played by Yeovil Town Football Club, an English football club based in Yeovil, Somerset.

Manager Gary Johnson signed nine players before the close of the summer transfer window. The season started promisingly with the club briefly topping the Football League One table in August before a 6-match losing run in September and October saw them drop in to mid-table. Having stood 12th in the league table after Boxing Day, Yeovil went on an 8-match run winning run which transformed them into promotion candidates. The signing of Paddy Madden permanently in January saw Yeovil win 11 of their final 20 games, and the team finished the season 4th in the table, a new record high finishing position, and qualified for the play-offs. Where they faced Sheffield United in the semi-final, a 1–0 away defeat in the first leg before a late Ed Upson goal gave Yeovil a 2–0 victory in the home leg. Brentford faced Yeovil in the 2013 Football League One play-off final at Wembley Stadium, Yeovil won 2–1 courtesy of goals from Madden and Dan Burn and were promoted to the second-tier of English football for the first time in the club's history.

Yeovil's first fixture of the season came in the League Cup first round, beating Colchester United before being defeated by Premier League side West Bromwich Albion in the second round. They were knocked out of the FA Cup by Preston North End in the first round and reached the Southern Area semi-finals of the Football League Trophy before being beaten by Leyton Orient. Paddy Madden was the club's and League One top scorer with 23 goals, with all but one of these coming in the league.
