The 1971 NCAA University Division swimming and diving championships were contested at the 35th annual swim meet sanctioned and hosted by the NCAA to determine the individual and team national champions of men's collegiate swimming and diving among its University Division member programs in the United States, culminating the 1970–71 NCAA University Division swimming and diving season.

These championships were hosted by Iowa State University at the Beyer Hall Pool on its campus in Ames, Iowa.

Three-time defending champions Indiana again topped the team championship standings, the Hoosiers' fourth NCAA national title.
