The 2022–23 St. Thomas Tommies men's basketball team represented the University of St. Thomas in the 2022–23 NCAA Division I men's basketball season.

The Tommies, led by 12th-year head coach John Tauer, played their home games at Schoenecker Arena in St. Paul, Minnesota as members of the Summit League.

As a result, the Tommies are not eligible for NCAA postseason play until 2026–27.

The Tommies participated in their first ever Division I conference tournament, as the Summit League announced the 2023 Summit League men's basketball tournament would include all 10 conference teams.

Because the Tommies were in the first year of a five-year transition period from DIII to DI, they were not eligible for NCAA postseason play, including the Summit League tournament.
