The St. Thomas Tommies women's basketball team represents the University of St. Thomas, located in Saint Paul, Minnesota, in NCAA Division I as a member of the Summit League.

The Tommies made their NCAA Division I debut under then-seventeenth-year head coach Ruth Opatz Sinn for the 2021–22 season.

The team plays its games at Schoenecker Arena on its campus in St. Paul.

They won the 1991 NCAA Division III National Champion beating Muskingum 73–55.

Sinn has helped guide the Tommies' moving from the Minnesota Intercollegiate Athletic Conference in Division III to the Summit League in Division I.
