The 1964 NCAA University Division basketball tournament involved 25 schools playing in single-elimination play to determine the national champion of men's NCAA Division I college basketball in the United States. It began on March 9, 1964, and ended with the championship game on March 21 in Kansas City, Missouri. A total of 29 games were played, including a third place game in each region and a national third place game.

UCLA, coached by John Wooden, won the national title with a 98–83 victory in the final game over Duke, coached by Vic Bubas. Walt Hazzard of UCLA was named the tournament's Most Outstanding Player. The title was the first in the history of the UCLA program, and was a sign of things to come, as the Bruins would win nine more championships in the next eleven seasons.
