2011 NCAA Division II men's basketball tournament

The 2011 NCAA Division II men's basketball tournament involved 64 schools playing in a single-elimination tournament to determine the national champion of men's NCAA Division II college basketball as a culmination of the 2010–11 basketball season. The winner was Bellarmine; the tournament's Most Outstanding Player was Jet Chang of runner-up BYU–Hawaii, the first player from a losing team to earn that honor in the Division II tournament since 1998.

The 2010 champion Cal Poly Pomona did not qualify for the tournament, while runner-up Indiana (PA) did. Along with Bentley, Midwestern State, and Augusta State, Indiana was one of four teams from the 2010 Elite Eight to qualify.

Qualification and tournament format
The champions of the 22 Division II basketball conferences qualified automatically. An additional 42 teams were selected as at-large participants by the tournament selection committee. The first three rounds of the tournament were organized in regions comprising eight participants in groups of two or three conferences (two in the Central and Midwest regions).
