1991 NCAA Division I women's volleyball tournament

The 1991 NCAA Division I women's volleyball tournament began with 32 teams and ended on December 21, 1991, when UCLA defeated Long Beach State 3 games to 2 in the NCAA championship match.

UCLA won the program's third NCAA title and successfully defended their 1990 NCAA title by defeating Long Beach State in five games. After losing the first two games by the scores of 15-12, 15-13, UCLA completed off a stunning comeback to take the next three games, 15-12, 15-6, 15-11 to win it all.

UCLA's comeback was one of the biggest in NCAA history; only one other team had ever rallied from two games to 0 to win in five games in the NCAA national championship (and did not again until 2009). UCLA finished their season 31-5.

The 1991 Final Four was held on the campus of UCLA at Pauley Pavilion.
