Denzel Edwin "Denny" Crum (born March 2, 1937) is an American former men's college basketball coach at the University of Louisville from 1971 to 2001, compiling a 675–295 (.696) record. He guided the Cardinals to two NCAA championships (1980, 1986) and six Final Fours. Honored in the Naismith Memorial Basketball Hall of Fame since 1994, Crum is one of the major figures in the history of sports in Kentucky and in college basketball in general.

As the head coach at U of L, Crum is widely credited with pioneering the now-common strategy of scheduling tough non-conference match-ups early in the season in order to prepare his teams for March's NCAA tournament, where one defeat ends the season. Crum's prolific post-season play and calm demeanor earned him the monikers "Mr. March" and his most well-known nickname, "Cool Hand Luke."
