The 2003 Kansas City Chiefs season resulted in a 13–3 record, beginning with a nine-game winning streak—the franchise’s best start in their 40-year history. The Chiefs won the AFC West and clinched the second seed in the playoffs. Kansas City lost in an offensive shootout at home in the AFC Divisional Playoffs to the Indianapolis Colts 38–31, a game notorious for involving no punts from either team's kicking squad.
