The 2011 season was the Arizona Cardinals' 92nd in the National Football League (NFL), their 24th in Arizona and their fifth under head coach Ken Whisenhunt. This was going to be the Cardinals first season with new starting quarterback Kevin Kolb, but he was injured and replaced by John Skelton. Despite a 1-6 start the Cardinals managed to win 7 out of 9 games, including a stunning upset against the San Francisco 49ers in week 14. The team improved on their 5–11 record from the 2010 season, but missed the playoffs for a second consecutive season.

The 2011 Cardinals won four overtime games, an NFL record that would later be matched by the 2021 Las Vegas Raiders.
