The 2015 Chicago Bears season was the franchise's 96th season in the National Football League. After the firing of general manager Phil Emery and head coach Marc Trestman following the 2014 season, the team hired former New Orleans Saints director of player personnel Ryan Pace and Denver Broncos head coach John Fox to fill those positions, respectively. Fox's hiring marked the Bears' third head coach in four seasons.

John Fox is an American football coach and former player who previously was a senior defensive assistant for the Detroit Lions of the National Football League (NFL). He was the head coach of the Carolina Panthers (2002–2010), Denver Broncos (2011–2014) and Chicago Bears (2015–2017) of the National Football League (NFL). He coached the Panthers to Super Bowl XXXVIII and the Broncos to Super Bowl XLVIII.
