2024 NCAA Division II men's basketball tournament

The 2024 NCAA Division II men's basketball tournament was a single-elimination tournament to determine the national champion of men's NCAA Division II college basketball in the United States, the culmination of the 2023–24 NCAA Division II men's basketball season.

The tournament again featured 64 teams, with teams placed into one of eight geographically oriented, eight-team regionals. The first three rounds were played on campus sites while the national quarterfinal (Elite Eight), semifinal, and championship rounds were held at the Ford Center in Evansville, Indiana, from March 26–30, 2024.

Minnesota State topped defending champions Nova Southeastern 88–85 in the championship game, on a three-pointer by Kyreese Willingham with 0.8 seconds left to win their first national championship. In the process, the Mavericks also completed a sweep of both the men's and women's Division II basketball championships for 2024, something that had only previously been done by Central Missouri in 1984. The Maverick women won their national championship, defeating Texas Woman's, 89–73.

Lincoln (PA), Post, and William Jewell participated in the tournament for the first time.

Regionals
First, second, and third-round games (the last of which serve as a regional championship), took place on campus sites from March 15–19, 2024. The top-seeded team in each regional served as host.

Elite Eight
The national quarterfinals quarterfinals, semifinals, and finals are being held at a predetermined site, the Ford Center in Evansville, Indiana, from March 26–30, 2024.

Qualifying
A total of 64 bids were 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 23 Division II conferences that sponsor men's basketball.
