The 1988 Western Illinois Leathernecks football team represented Western Illinois University as a member of the Gateway Collegiate Athletic Conference during the 1988 NCAA Division I-AA football season. They were led by sixth-year head coach Bruce Craddock and played their home games at Hanson Field. The Leathernecks finished the season with a 10–1 record overall and a 6–0 record in conference play, making them the conference champions. Senior and 4-year starter Paul Singer was the Leathernecks' quarterback. He was selected to five All-American teams, as well as being a GTE and NCAA Academic All-American, the Conference Player of the Year, and the national Player of the Year runner-up. He held nearly every WIU passing and offensive record, as well as several conference records. The 10 wins were the most in the nearly 100-year history of WIU football.
