2011 CollegeInsider.com Postseason Tournament

The 2011 CollegeInsider.com Postseason Tournament (CIT) was a postseason single-elimination tournament of 24 NCAA Division I teams. The CIT began with 12 first-round games. Four of the teams that won first-round games advanced to the quarterfinals, while the other eight teams played for the right to advance to the quarterfinals in the second round March 18–19. The announcement of the 2011 field was made on March 13, 2011.

Twenty-three of the participants were selected from teams that were not invited to the 2011 NCAA Tournament or the 2011 National Invitation Tournament. The winner of the 2011 Great West Conference men's basketball tournament, North Dakota, received an automatic bid to the CIT.

The tournament was won by Santa Clara who defeated Iona in the championship game 76–69. Santa Clara was not one of the four teams to receive a second-round bye thus becoming the first team to win five games to win the tournament championship.
