Kevin Scott Fagan (born April 25, 1963 in Lake Worth, Florida) is a former American football defensive end who played eight seasons (from 1987 to 1994) for the San Francisco 49ers of the National Football League. Fagan was regarded as one of the best run stopping defensive lineman in professional football, until several injuries including back, shoulder, and knee issues forced him to retire following the 1994 season. In 1990, Fagan earned second team UPI all-pro honors. 
Fagan was one of the NFL's strongest men, having recorded a Miami school record 560 pound bench press. 
Fagan graduated in 1981 from John I. Leonard High School in Lake Worth, where he played football and track and field. He played college football at the University of Miami and is a member of the UM Sports Hall of Fame.
