2015 NCAA Division I baseball tournament

The 2015 NCAA Division I baseball tournament began on Friday, May 29, 2015, as part of the 2015 NCAA Division I baseball season. The 64-team double-elimination tournament concluded with the 2015 College World Series in Omaha, Nebraska, which began on June 13 and ended on June 24 with the Virginia Cavaliers upsetting the defending champion Vanderbilt Commodores 4–2 in the decisive Game 3 and thereby avenging their CWS Finals loss to Vanderbilt the previous year.

The 64 participating NCAA Division I college baseball teams were selected out of an eligible 298 teams. Thirty-one teams were awarded an automatic bid as champions of their conferences, and 33 teams were selected at-large by the NCAA Division I Baseball Committee.

Teams were divided into 16 regionals of four teams, which conducted a double-elimination tournament. Regional champions then faced each other in Super Regionals, a best-of-three series to determine the eight participants of the College World Series.

Vanderbilt University and the University of Virginia split the first two games of the best-of-three championship series before Virginia won Game 3, 4–2, to win their first national championship in baseball. The two teams previously met in the championship series in 2014, which Vanderbilt won.
