2023 NCAA Division II men's basketball tournament

The 2023 NCAA Division II men's basketball tournament was the single-elimination tournament to determine the annual national champion of men's NCAA Division II college basketball in the United States.

The championship rounds were held from March 21–25, 2023 at the Ford Center in Evansville, Indiana.

Nova Southeastern won their first ever national championship, beating West Liberty 111–101 in the championship game. The Sharks also completed a perfect 36–0 season, the first team to do so since Northwest Missouri State in 2019.

McKendree and North Georgia participated in the tournament for the first time, with both winning tournament games, and the former making it to the Regional Final.

Regionals
First, second, and third-round games (the last of which doubles as a regional championship), will take place on campus sites from March 11–14, 2023. The top-seeded team in each regional serves as host.

Elite Eight
The national quarterfinals, semifinals, and finals will be held at a predetermined site, the Ford Center in Evansville, Indiana, from March 21–25, 2023.

Qualifying
A total of sixty-four bids are available for the tournament: 23 automatic bids (awarded to the champions of the twenty-three Division II conferences) and 41 at-large bids.

The bids are allocated evenly among the eight NCAA-designated regions (Atlantic, Central, East, Midwest, South, South Central, Southeast, and West), each of which contains either two or three of the twenty-three Division II conferences that sponsor men's basketball.
