1991 NCAA Division I men's soccer tournament

The 1991 NCAA Division I men's soccer tournament was the 33rd annual tournament organized by the National Collegiate Athletic Association to determine the national champion of men's collegiate soccer among its Division I members in the United States.

Virginia defeated Santa Clara in the championship game in a penalty kick shootout (3–1) after the match ended in a 0–0 tie after four overtime periods. This was a re-match of the 1989 tournament final at Rutgers Stadium when both teams were crowned co-national champions (before the NCAA adopted penalty kick shootouts for settling tied games).

The final match was played on December 8 at the USF Soccer Stadium in Tampa, Florida. All the other games were played at the home field of the higher seeded team.

Qualifying
Five teams made their debut appearances in the NCAA Division I men's soccer tournament: Florida International, Furman, Hartford, UNC Charlotte, and Tulsa.
