This is a list of qualifying teams for the 2009 NCAA Men's Division I Basketball Tournament. A total of 65 teams entered the tournament. Thirty of the teams earned automatic bids by winning their conference tournaments. The automatic bid of the Ivy League, which does not conduct a post-season tournament, went to its regular season champion. The remaining 34 teams were granted at-large bids, which are extended by the NCAA Selection Committee. All teams are seeded 1 to 16 within their regionals, while the Selection Committee seeded the entire field from 1 to 65.
