The 1981 NCAA Men's Division I Swimming and Diving Championships were contested in March 1981 at the Texas Swimming Center at the University of Texas at Austin in Austin, Texas at the 58th annual NCAA-sanctioned swim meet to determine the team and individual national champions of Division I men's collegiate swimming and diving in the United States.
Hosts Texas topped the team standings for the first time, the Longhorns' inaugural national title.
