The 2003 Indianapolis Colts season was the 51st season for the team in the National Football League (NFL) and 20th in Indianapolis. The Colts improved on their 10–6 record from 2002, going 12-4 and reached the postseason for the second straight season. After the season, quarterback Peyton Manning was named league MVP along with Steve McNair of the Tennessee Titans.
After defeating the Denver Broncos and the Kansas City Chiefs in the first two rounds, the Colts lost to the New England Patriots in the AFC Championship Game, which saw the first playoff meeting between Tom Brady and Peyton Manning. The Patriots defeated the Carolina Panthers in Super Bowl XXXVIII. This was the final season that the team wore blue facemasks on the helmets.
