2011 Arizona Wildcats football team

The 2011 Arizona Wildcats football team represented the University of Arizona in the 2011 NCAA Division I FBS football season. The team played their home games in Arizona Stadium in Tucson, Arizona. This was the first year for Arizona in the newly reconfigured Pac-12 Conference; they played in the Pac-12 South Division. They finished the season 4–8, 2–7 in Pac-12 play.

The team was coached by interim head coach Tim Kish for the last six games of the season after eighth-year head coach Mike Stoops was fired as head coach on October 10 after starting the season 1–5 (their sole victory was against FCS Northern Arizona). Including the previous season, the Wildcats under Stoops had lost 10 consecutive games against FBS opponents, with their last victory over a FBS team taking place nearly a year earlier on October 30, 2010, against UCLA. Kish, the team's defensive coordinator, was named interim head coach for the remainder of the season. Kish finished the season 3–3, including a Duel in the Desert victory over Arizona State to reclaim the Territorial Cup. Rich Rodriguez was named the Wildcats' new full-time head coach starting in 2012.
