2013 Indianapolis Colts season

The 2013 season was the Indianapolis Colts' 61st in the National Football League (NFL), their 30th in Indianapolis and their second under head coachChuck Pagano, who missed most of the 2012 season due to treatment for leukemia. Throughout the season, the Colts wore a patch to recognize the 30th season since their move to Indianapolis.

While losing their Week 14 match-up against the Cincinnati Bengals, the Colts clinched their 15th division title after the Denver Broncos defeated the Tennessee Titans and their first without Peyton Manning. The Colts matched their 2012 record of 11–5, and went undefeated within the division during the season.

In the AFC wild card game against the Kansas City Chiefs, the Colts rallied to turn a 38–10 Chiefs' lead into a 45–44 victory for the second-largest comeback in NFL playoff history. It is behind the Buffalo Bills who rallied from a 32-point deficit in the 1993 AFC Wild Card Game. The Colts' season came to an end with a 43–22 loss to the New England Patriots in the divisional round.
