2023 Indianapolis Colts season

The 2023 season was the Indianapolis Colts' 71st season in the National Football League (NFL) and their 40th in Indianapolis. It was also their seventh under the leadership of general manager Chris Ballard and the first under new head coach Shane Steichen. Despite low expectations, the Colts improved on their 4–12–1 record from the previous season after a Week 10 victory over the New England Patriots in Frankfurt, and more than doubled their wins from the previous year, and finished with a 9–8 record. Unable to win the AFC South for the 9th consecutive season, they were eliminated from playoff contention in the final week of the season for the second time in three seasons after a loss to the Houston Texans.

Preseason
The Colts opened their 2023 preseason with a 23–19 loss to the Buffalo Bills on August 12, 2023. Anthony Richardson, the fourth overall selection in the 2023 NFL draft, started the game, completing seven of his 12 passes for 67 yards while being intercepted once. He was also credited with two carries for seven yards. Three days later, Richardson was named the team's starter for the regular season by first-year head coach Shane Steichen.
