1959 NCAA swimming and diving championships

The 1959 NCAA swimming and diving championships were contested on March 26−28, 1959 at Teagle Pool at Cornell University in Ithaca, New York at the 23rd annual NCAA-sponsored swim meet to determine the team and individual national champions of men's collegiate swimming and diving among its member programs in the United States. Including the pre-NCAA championships from before 1937, these were the 36th overall collegiate swimming and diving championships.

The program featured sixteen individual events, fourteen in swimming and two for diving. Teams earned points based on their placement in individual events, with the highest-earning team receiving the national title.

Michigan once again retained the national title, the Wolverines' ninth (and third consecutive), after finishing a record ninety-three points ahead of Ohio State in the team standings.
