The NCAA Men's Water Polo Championship is an annual tournament to determine the national champion of NCAA men's collegiate water polo. Beginning in 1969, it has been held every year except 2020, when it was postponed to March 2021 because of the COVID-19 pandemic. With a limited number of NCAA water polo programs at the national level, all men's teams, whether from Division I, Division II, or Division III, are eligible to compete each year in the National Collegiate tournament. The tournament was expanded from a four-team bracket in 2013 by adding two play-in games that are contested by the bottom four seeds, effectively creating a six-team bracket with a first-round bye for the top two teams. This makes it the sport with the fewest teams reaching the NCAA tournament; this is because there are only 43 men's water polo teams between all three NCAA divisions.
The NCAA Women's Water Polo Championship has existed since the 2001 season. Seven conferences have teams competing in women's water polo: the Big West Conference, the Collegiate Water Polo Association (CWPA), the single-sport Golden Coast Conference, the Metro Atlantic Athletic Conference (MAAC), the Mountain Pacific Sports Federation (MPSF), the Southern California Intercollegiate Athletic Conference (SCIAC) and the Western Water Polo Association (WWPA). Some teams compete at Division III either as members of the Southern California Intercollegiate Athletic Conference or independently. Teams qualify by either winning their respective conference tournament or receiving one of the few at large bids available. Unlike most NCAA sports, only one National Collegiate championship is held each season with teams from Division I, Division II, and Division III competing together.
The UC Irvine Anteaters are the athletic teams fielded by the University of California, Irvine. Its athletics programs participate in the NCAA's Division I, as members of the Big West Conference and the Mountain Pacific Sports Federation. For earlier years of the school's existence, the teams participated at the Division II level with great success as explained below.
