The NCAA Division II men's basketball tournament (officially styled by the NCAA as a "Championship" instead of a "Tournament") is an annual championship tournament for colleges and universities that are members of NCAA Division II, a grouping of schools in the United States (plus one school in Canada) that are generally smaller than the higher-profile institutions grouped in Division I. The tournament, originally known as the NCAA College Division Basketball Championship, was established in 1957, immediately after the NCAA subdivided its member schools into the University Division (today's Division I) and College Division. It became the Division II championship in 1974, when the NCAA split the College Division into the limited-scholarship Division II and the non-scholarship Division III, and added the "Men's" designation in 1982 when the NCAA began sponsoring a Division II women's championship. Like all other NCAA basketball divisions for men and women, the champion is decided in a single-elimination tournament. The Division II tournament normally involves 64 teams. The Division II tournaments for men and women differ in a major respect from those in Divisions I and III. The finals of both Division II tournaments consist of eight teams, instead of the four in the other two divisions. The eight survivors of regional play meet in the Elite Eight at a predetermined site.

Qualification

A total of 64 bids are normally available for each tournament: 23 automatic bids (awarded to the champion of each Division II all-sports conference) and 41 at-large bids. Due to COVID-19 issues, the 2020 tournament was canceled, and the 2021 tournament was reduced to 48 teams when nine all-sports conferences chose not to compete in men's basketball in 2020–21. The bids are allocated evenly among the eight NCAA-designated regions (Atlantic, Central, East, Midwest, South, South Central, Southeast, and West), all but one of which contain three of the 23 Division II conferences that sponsor men's basketball. The South Central region contains only two conferences. Each regional tournament involves an appropriate number of automatic qualifiers (teams that won their respective conference tournaments), with the remaining participants entering via at-large bids (which are awarded regardless of conference affiliation).
