The 2023–24 St. Thomas Tommies men's basketball team represented the University of St. Thomas in the 2023–24 NCAA Division I men's basketball season. The Tommies, led by 13th-year head coach John Tauer, played their home games at Schoenecker Arena in St. Paul, Minnesota as members of the Summit League.
This season marked St. Thomas's third year of a five-year transition period from Division III to Division I, an incredibly rare and historic jump that bypasses Division II altogether. As a result of this transition, the Tommies are not eligible for NCAA postseason play until 2026–27. The Tommies participated in their second ever Summit League men’s Basketball tournament, defeating North Dakota State in the Quarterfinals before falling to top seeded South Dakota State in the semifinals.
The Tommies finished the 2022–23 season 19–14, 9–9 in Summit League play to finish in a tie for fourth place. Since the Summit League expanded the Summit League men's basketball tournament to include all league teams, St. Thomas played in their first Division I postseason tournament. They defeated Western Illinois in the quarterfinals,[1] and lost to Oral Roberts in the semifinals.[2]
