The 1930 NCAA basketball tournaments, now known as the NCAA Season 6 basketball tournaments, are the basketball tournaments of the National Collegiate Athletic Association (Philippines) (NCAA) for its 1930–31 season. Two tournaments were held, the seniors' tournament for male collegiate players, and the midgets' tournament, for male high school students.
The tournaments began on August 14, 1930, with Tomas Earnshaw, the mayor of Manila, performing the ceremonial toss, and ended on November 6, 1930.
The University of Santo Tomas (UST) won the seniors' tournament, their first, and to date, only NCAA basketball title. Meanwhile, San Juan de Letran College won their third consecutive midgets' championship.
