NCAA Division I Outdoor Track and Field Championships – Men's 400 meter intermediate hurdles

This is a list of the NCAA outdoor champions in the 440 yard hurdles until 1975, and the metric 400 meters hurdles being contested in Olympic years starting in 1932. Metrication occurred in 1976, so all subsequent championships were at the metric distance. Hand timing was used until 1973, starting in 1974 fully automatic timing was used.
