The 2015 NCAA Division I men's basketball tournament involved 68 teams playing in a single-elimination tournament that determined the National Collegiate Athletic Association (NCAA) Division I men's basketball national champion for the 2014–15 season. The 77th edition of the tournament began on March 17, 2015, and concluded with the championship game on April 6, at Lucas Oil Stadium in Indianapolis, Indiana.

The Final Four consisted of Kentucky (who went in undefeated at 38–0), Wisconsin, making their second consecutive trip to the Final Four, Michigan State, making their first Final Four since 2010 (also held in Indianapolis) and the 7th under head coach Tom Izzo, and Duke, making their first appearance since their 2010 national championship. Duke defeated Wisconsin in the championship game, 68–63, clinching their 5th national championship under Mike Krzyzewski. Tyus Jones of Duke was the tournament's Most Outstanding Player.
