2024 NCAA Division III men's basketball tournament

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

The tournament again featured sixty-four teams, with teams placed into one of four sixteen-team regionals. The first four rounds were played on campus sites while the national and semifinal championship rounds were held at the Allen County War Memorial Coliseum in Fort Wayne, Indiana from March 14–16, 2024.

In their first–ever Division III tournament, Trine won the national championship, beating Hampden–Sydney 69–61.

Five teams made their first appearances in the NCAA Division III tournament: Geneva, Mary Baldwin, Roger Williams, SUNY New Paltz, and Trine.

Qualifying teams
A total of sixty-four bids were available for the tournament: 42 automatic bids—awarded to the champions of the forty-two NCAA-recognized Division III conference tournaments—and 22 at-large bids.

There was a net decrease of two automatic bids this year, due to the automatic bids for the Colonial States Athletic Conference (whose members were folded into the United East Conference) and the New England Collegiate Conference (whose remaining full members all departed after the last season) having been eliminated. Starting next year, the Collegiate Conference of the South will get an automatic bid.

Automatic bids (42)
The following 42 teams are automatic qualifiers for the 2024 NCAA field by virtue of winning their conference's automatic bid (except for the UAA, whose regular-season champion received the automatic bid).

At-large bids (22)
The following 22 teams were awarded qualification for the tournament field by the NCAA Division III Men's Basketball Committee. The committee evaluated teams on the basis of their win–loss percentage, strength of schedule, head-to-head results, results against common opponents, and results against teams included in the NCAA's final regional rankings.
