The 1985 NCAA Division I Men's Tennis Championships were the 39th annual championships to determine the national champions of NCAA Division I men's singles, doubles, and team collegiate tennis in the United States.

The Bulldogs defeated defending national champion UCLA in the final round, 5–1.

Pernfors became the first person to win back-to-back single's titles since Dennis Ralston in 1963 and 1964.

The men's doubles title was won by Kelly Jones and Carlos DiLaura from Pepperdine.

It was also Jones' second consecutive double's title, the first player to do this since Mel Purcell and Rodney Harmon in 1980 and 1981.
