2003 NCAA Division I baseball tournament

The 2003 NCAA Division I baseball tournament was held May 30 through June 23, 2003. Sixty-four NCAA Division I college baseball teams met after having played their way through a regular season, and for some, a conference tournament, to play in the NCAA tournament. The tournament culminated with 8 teams in the College World Series at historic Rosenblatt Stadium in Omaha, Nebraska.

ESPN, which held the rights to the College World Series, began televising super regional games in 2003. As part of the contract with ESPN, four super regionals would begin on Friday and run through Sunday, while the other four super regionals would begin Saturday and run through Monday.

The 2003 College World Series saw a format change and the championship was decided by a best-of-three series. From 1950 through 1987, the College World Series was a true double elimination tournament. From 1988 through 2002, there were two double elimination pools, with the winner of each facing off in a one game championship.

In the 2003 championship series, Rice defeated Stanford two games to one. John Hudgins became the 16th player to win the College World Series Most Outstanding Player Award from a losing team.
