The NCAA Season 80 basketball tournaments are the postseason tournaments of the National Collegiate Athletic Association for basketball at the 2004–05 season. The tournaments are divided into two divisions: the Juniors tournament for male high school students and the Men's tournament for male college students.

The NCAA ushered its 80th season on June 26, 2004 before a packed crowd at the Araneta Coliseum. Ricky Palou is the year's NCAA commissioner, the opening rites were graced by the NCAA board members and other representatives of member schools.

Philippine Christian University bagged their first-ever NCAA crown since joining the league eight years ago. The Dolphins swept the University of Perpetual Help Altas.
