This is a list of qualifying teams for the 2015 NCAA Division I men's basketball tournament. A total of 68 teams entered the tournament. Thirty-one of the teams earned automatic bids by winning their conference tournaments. The automatic bid of the Ivy League, which did not conduct a postseason tournament, went to its regular season champion. The remaining 36 teams were granted at-large bids, which were extended by the NCAA Selection Committee. All teams were seeded 1 to 16 within their regionals, while the Selection Committee seeded the entire field from 1 to 68.
