The 2010–11 English football season was Wigan Athletic F.C.'s 33rd season in the Football League and their sixth consecutive season in the Premier League.

Following a mixed first season in charge of the club, manager Roberto Martínez decided to make several additions to the playing squad. Wigan's most expensive summer signing was Argentine striker Mauro Boselli, who signed for an undisclosed fee believed to be in the region of £6 million. Dutch defender Mario Melchiot and Austrian midfielder Paul Scharner both left the club after their contracts expired. Gary Caldwell was named as the new club captain.

There were also changes behind the scenes, with general manager John Benson leaving the club to join Sunderland, re-uniting with former Wigan manager Steve Bruce. Director Maurice Lindsay also stepped down to take up the position of chairman at Preston North End.

Wigan's first pre-season friendly was a 3–2 win against Östersunds FK, with new signing Boselli scoring twice. Their next friendly was a 1–1 draw against Oldham Athletic, featuring trialists Laurent Merlin and Sekou Baradji. Baradji also joined the squad at their pre-season training camp in Austria, but would ultimately not be offered a contract.
