The NCAA Season 100 basketball tournaments were the basketball tournaments of the National Collegiate Athletic Association (Philippines) (NCAA) for its 2024âÂÂ25 season. The tournament was hosted by Lyceum of the Philippines University. Opening day of the men's tournament was held at the SM Mall of Asia Arena on September 7, 2024, while the rest of the elimination round games was held at the Filoil EcoOil Centre, then the final elimination gameday and semifinals held at the Cuneta Astrodome, then the finals at the Araneta Coliseum. The juniors' tournament started on February 24, 2025, and ended on April 15, 2025.
The Mapúa Cardinals won their first men's championship since NCAA Season 67 (1991), defeating the Benilde Blazers. Mapúa finished first at the end of the elimination round and defeated the Lyceum Pirates in the semifinals. Benilde finished second, and ousted the defending champions San Beda Red Lions in the other semifinal.
The Perpetual Junior Altas won the first juniors' championship. They defeated the La Salle Green Hills Greenies in the finals. Perpetual finished the elimination round first, with Letran, LSGH and San Beda tied for second, with the three teams ranked by tiebreakers. LSGH eliminated defending champions Letran, while Perpetual defeated San Beda. San Beda won third place, while Perpetual clinched the first basketball title for their school in the deciding game three of the finals.
The NCAA used the Final Four format used since 1997.
The NCAA mulled in moving the seniors' tournament to the second semester, and the juniors' tournament to the first semester. Reasons for the move include struggles in adjusting its calendar as a 10-team league, and for a more "unified" college basketball season; the move would have also allowed the juniors' tournament to revert to a double round robin elimination round format.
The plans did not push through, as the league opted to have the seniors' tournament in the first semester of the academic year. Unlike in the past two seasons, while men's gamedays are held five days a week, all gamedays was scheduled to be doubleheaders, except for the final playing day of the first round of eliminations, which shall be a single game involving last year's finals participants.
The NCAA appointed Ogie Bernarte as basketball commissioner for this season. However, both Bernarte and his mother fell ill as the first round of the eliminations was ending. He was replaced by Joel Ngo starting at the second round. While both Bernarte and his mother recovered, the NCAA decided to retain Ngo to avoid another transition, and instead made Bernarte a consultant.
The third place playoff, introduced last season, was originally included in the tournament. However, due to logistical issues, the NCAA decided to cancel it for the men's tournament.
The juniors' basketball tournament continued to have a single round-robin elimination round, with all teams playing one game day, with a week having at least 3 game days
All ten schools participated.
For the men's tournament, the SM Mall of Asia Arena in Pasay hosted opening day, while Filoil EcoOil Centre in San Juan hosted the remainder of the elimination round. The last two game days of the first round which were originally to be held at the Filoil EcoOil Centre were then made into a tripleheader held at the SM Mall of Asia Arena. The second gameday postponed by Tropical Storm Kristine (Trami), and the semifinals was held at the Cuneta Astrodome in Pasay. The finals was then held at the Araneta Coliseum in Quezon City.
For the juniors' tournament, elimination round games are split on the Emilio Aguinaldo College (EAC) Sports and Cultural Center in Manila for Sunday gamedays, and on the Filoil EcoOil Centre for gamedays on other days of the week.
Each team can have up to 15 players on their roster, with an additional up to three players in the injured reserve list.
The ban of foreign student-athletes first applied in Season 96 (2020) is still in effect, requiring all players to be Filipinos.
