2011 Big Sky Conference Men's Basketball Tournament

The 2011 Big Sky Men's Basketball Tournament was played from March 5 to March 9, 2011. The First Round games of the tournament were held at the higher seed's home arena, and the semi-finals and championship were at the Butler–Hancock Sports Pavilion in Greeley, Colorado, home court of the regular season champion, Northern Colorado. The top 6 teams from regular season play qualified for the tournament, and the top 2 teams received a bye to the semi-finals. The field was re-seeded after the first round so the #1 seed played the lowest remaining seed. In 2011, Northern Colorado won the conference championship to advance to its first NCAA Division I tournament in school history.
