The NCAA basketball championships are the basketball championships of the National Collegiate Athletic Association (Philippines) (NCAA). There are two tournaments, usually held at the same time, the seniors' tournament for male collegiate students, and the juniors' tournament for male senior high school students. If a school wins both championships in one season, it said that they have won the "double championship."
The tournament commences with a double-round robin of eliminations, where the four teams with the best records advance to the semifinals, with the two top seeds clinching the twice-to-beat advantage. The winners in the semifinals meet in a best-of-3 finals series, in order to determine the champion.
The championship is continually contested since the NCAA's foundation in 1924, except during World War II, during the mid-1960s when scandals rocked the association, in 1980 when the tournament was aborted by the Basketball Association of the Philippines, and from 2020 to 2021 during the COVID-19 pandemic.
The athletic nicknames of the different teams variously came from the school's founders, or from a distinct quality that separated a school from the others.
Notably, the first champion of this event was crowned in 1925, 14 years before the U.S. NCAA tournament was instituted.
