The National Association of Intercollegiate Athletics men's basketball national championship has been held annually since 1937. The tournament was established by James Naismith to crown a national champion for smaller colleges and universities. Through the 2019–20 season, the NAIA Tournament featured 32 teams, and the entire tournament was contested at one location in one week, rather than multiple locations over a series of weekends. Beginning with the 2021 edition, the tournament expanded to 48 teams, starting with play at 16 regional sites, with only the winners at these sites playing at the final venue. The 2022 tournament expanded again to 64 teams. From 1992 to 2020, the NAIA sponsored a Division II championship. The Division I tournament is played in Kansas City, Missouri, while in 2020, the Division II tournament was to be held for the last time at the Sanford Pentagon in Sioux Falls, South Dakota; however, the tournaments were called off due to the COVID-19 pandemic. The NAIA returned to a one-division setup in 2021. The NAIA games can be watched online through the official NAIA provider StretchInternet.
