Original Umbro football shirt Swansea City 2010/11

The 2010–11 season was Swansea City's 82nd season in the Football League. They finished in 3rd place, and won the Championship playoff, to win promotion to the Premier League. It was their first return to top-flight football since 1983.

The season was their third consecutive season in the second tier following a 7th-placed finish in the previous campaign, narrowly missing out on a play-off place.

During pre-season, Paulo Sousa left the club by mutual consent, and then later succeeded Nigel Pearson as the new Leicester City manager on 7 July. Brendan Rodgers was appointed as the new manager of Swansea on 16 July, on a 12-month rolling contract.
