The 2015 Illinois Fighting Illini football team represented the University of Illinois at Urbana–Champaign in the 2015 NCAA Division I FBS football season. They were led by interim head coach Bill Cubit, and played their home games at Memorial Stadium. They were members of the West Division of the Big Ten Conference. They finished the season 5–7, 2–6 in Big Ten play to finish in a tie for fifth place in the West Division.
The 2014 Illinois Fighting Illini football team finished the regular season 6–6, with a highlight win against Northwestern which brought the team bowl eligible and was invited to play in the 2014 Heart of Dallas Bowl against the Louisiana Tech Bulldogs of Conference USA. The Bulldogs defeated the Illini in Dallas, Texas 35–18 finishing their 2014 Season at 6–7.
On August 28, 2015—one week before the start of the regular season—head coach Tim Beckman was fired after an internal investigation found that he had made efforts "to deter injury reporting and influence medical decisions that pressured players to avoid or postpone medical treatment and continue playing despite injuries." He was replaced by offensive coordinator Bill Cubit on an interim basis for the season.
A few hours before the final game of the season, Cubit had the "Interim" removed from his title and was named permanent head coach. It was an appointment that would last only one game, as Cubit was removed during the following off-season by new Illinois Athletic Director Josh Whitman, on the day Whitman officially assumed the role, in favor of former Chicago Bears and Tampa Bay Buccaneers head coach Lovie Smith.
