1999 Indianapolis Colts season

The 1999 Indianapolis Colts season was the 47th season for the team in the National Football League and 16th in Indianapolis. The Indianapolis Colts finished the National Football League's 1999 season with a record of 13 wins and 3 losses, and won the AFC East for the first time since 1987. This was the franchise's first 10 win season since 1977, when they were still in Baltimore. This season resulted in the franchise's first playoff appearance since 1996.

This season marked a turning point for the Colts franchise, as the team had only made the playoffs three times since 1977. Since 1999, the Colts have been one of the more successful NFL franchises, with 15 playoff appearances, two AFC Championships, and earning a Super Bowl title in Super Bowl XLI. This was the first time a team had done a 10-game single-season turnaround, and since then only the 2008 Miami Dolphins and 2025 New England Patriots have been able to match it.

Despite completing a great turnaround from 3–13 to 13–3, the Colts would go on to lose to the eventual AFC Champion Tennessee Titans in the Divisional Round of the playoffs. After the 1999 season, the Colts never reached the top of the AFC East again, moving to the new AFC South division in 2002.

In the 1999 NFL Draft the Colts selected right guard Brandon Burlsworth with the 63rd overall pick. Tragically, days before he signed with the Colts and being named a starter, he was killed in a road accident with a semitruck.
