The 1973 NCAA University Division Tennis Championships were the 28th annual tournaments to determine the national champions of NCAA University Division men's singles, doubles, and team collegiate tennis in the United States.[1] This was the final year before the NCAA changed the name of its University Division to its present-day moniker, Division I.
Stanford, the previous year's runners-up, captured the team championship, the Cardinal's first such title. Stanford finished five points ahead of USC in the final team standings (33–28).
