Ron Zook (born April 28, 1954 in Loudonville, Ohio) is an American football coach and the current head coach at the University of Illinois.
Ron Zook played college football as a defensive back for Miami University, and graduated with a bachelor's degree in 1976. Zook immediately began coaching football, beginning at Orrville High School in Orrville, Ohio in 1976. In 1978, Zook moved to coaching college football, beginning at Murray State University. Through the 1980s, Zook held coaching positions at a number of schools, including Cincinnati, Kansas, Tennessee, Virginia Tech, and Ohio State University.
Beginning in 1991, Zook served as defensive coordinator for three seasons at the University of Florida under head coach Steve Spurrier. After the 1993 season, Spurrier reassigned Zook to be the special teams coordinator, a move considered by many to be a demotion. Nonetheless, in 1995, Spurrier added the title of associate head coach to Zook's position.
