The 1957 NCAA University Division baseball tournament was played at the end of the 1957 NCAA University Division baseball season to determine the national champion of college baseball.
Eight regional districts sent representatives to the College World Series with preliminary rounds within each district serving to determine each representative.
Each district had its own format for selecting teams, resulting in 23 teams participating in the tournament at the conclusion of their regular season, and in some cases, after a conference tournament.
The eleventh tournament's champion was California, coached by George Wolfman.
The Most Outstanding Player was Cal Emery of Penn State.
