100 meters at the NCAA Division I Outdoor Track and Field Championships

This is a list of the NCAA Division I outdoor champions in the shortest sprint event. Since 1921, the men's 100-yard dash was usually held until 1975, with the exception of the 100 meters being contested in Olympic years starting in 1932. Metrication occurred in 1976, so all subsequent championships (as well as those during some Olympic years before 1976) were at the metric distance. Hand timing was used until 1973, while starting in 1974 fully automatic timing was used. Wind speeds were not consistently recorded until 1963. The women's championships began in 1982.
