NCAA men's water polo championship

The NCAA men's water polo championship is an annual tournament organized by the National Collegiate Athletic Association to determine the national champion of men's collegiate water polo among its member programs in the United States. It has been held every year since 1969, except 2020 when it was postponed to March 2021 due to 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; currently, there are only 43 men's water polo teams between all three NCAA divisions.

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. Starting with the 2023 tournament, the number of teams was increased to eight teams. Even with this expansion, the men's water polo tournament remains the smallest across all NCAA sports.

While the championship often includes teams from around the country, most programs are located within the state of California, and no school from outside California has ever surpassed third place or participated in the NCAA Men's Water Polo Championship game.

The four California based Pac-12 schools have been the most successful. The University of California, Berkeley is the most successful program with 17 titles, followed by UCLA with 13 titles, Stanford (11 titles), and USC (10 titles). One of these four schools has won the championship every year since 1998.
