The 2010 NCAA Division 1 softball tournament was held from May 20 through June 8, 2010 and is part of the 2010 NCAA Division 1 softball season. The 64 NCAA Division 1 college softball teams were selected out of an eligible 284 teams on May 16, 2010. 30 teams were awarded an automatic bid as champions of their conference, and 34 teams were selected at-large by the NCAA Division 1 Softball Selection Committee. The tournament culminated with eight teams playing in the 2010 Women's College World Series at ASA Hall of Fame Stadium in Oklahoma City, Oklahoma. UCLA won their record 11th championship, defeating Arizona in the final.

Teams in "italics" advanced to super regionals. Teams in "bold" advanced to Women's College World Series.

Whereas in previous years, the outfield fence was set at 190 feet from home plate and standing four feet in height, the fence was moved back to 200 feet and raised to a height of six feet for this year's tournament. Despite the change, the 2010 Series saw a record-breaking number of home runs resulting from "some of the power brought into the game by composite-barreled bats."^[1]

The 2010 WCWS was marked by a proliferation of illegal pitch calls, following a memo by NCAA Softball Secretary Rules Editor Dee Abrahamson outlining an increased emphasis on legal pitching.^[2] Arizona Wildcats pitcher Kenzie Fowler, in particular, was cited for eight illegal pitches in Arizona's first-round 9-0 loss to Tennessee, and a further eight illegal pitches in Arizona's second-round 4-3 win over Washington; Fowler was cited for 16 of the 22 illegal pitches called in the first eight games of the tournament. Wildcats coach Mike Candrea reacted by saying that "the officials were way too involved in [the Tennessee] game," and that the citation of illegal pitches was "sporadic."^[3]
