The 2013 Big East men's basketball tournament, officially known as the 2013 Big East Championship, was the 34th annual Big East men's basketball tournament, deciding the champion of the 2012–13 Big East Conference men's basketball season. For the 31st consecutive season, the tournament was held at Madison Square Garden in New York City, from March 12–16, 2013. The tournament only featured 14 teams due to Connecticut being given a one-year postseason ban due to APR penalties. This would have been the last year with as many as 16 teams participating in the Big East tournament, but Connecticut was ineligible and West Virginia moved to the Big 12 before the beginning of the season. The conference tournament champion received an automatic bid to the 2013 NCAA tournament.
