The 2002 NCAA Division I Baseball Tournament was played at the end of the 2002 NCAA Division I baseball season to determine the national champion of college baseball. The tournament concluded with eight teams competing in the College World Series, a double-elimination tournament in its fifty sixth year. Sixteen regional competitions were held to determine the participants in the final event, with each winner advancing to a best of three series against another regional champion for the right to play in the College World Series. Each region was composed of four teams, resulting in 64 teams participating in the tournament at the conclusion of their regular season, and in some cases, after a conference tournament.[1] The fifty-sixth tournament's champion was Texas, coached by Augie Garrido. This was Texas' first title since 1983, but Augie Garrido previously won three titles with Cal State Fullerton. The Most Outstanding Player was Huston Street of Texas.

Due to fears over terrorism and travel security in the wake of the September 11 attacks, the Division I Baseball Committee, which selects the 64-team field and places the teams on the bracket, was ordered by the NCAA to keep regional pairings as localized as possible, in order to minimize the number of plane trips utilized. Due to these travel constraints, teams from the same conference were allowed to play in the same regional for the first time. An example of the travel restrictions came from the regional in Baton Rouge, Louisiana, featuring four schools from the Bayou State which are located a total of 130 miles (210 km) apart along Interstate 10, the first time (and to date, last) a regional has been entirely an in-state affair outside California, Florida, and Texas. The travel restrictions were eased in 2003, and the ban on conference teams facing each other in regional play was reinstated.
