The 2003 Denver Broncos season was the franchise's 34th season in the National Football League (NFL) and the 44th overall.
After the departure of Brian Griese, who signed with his father's team, the Dolphins, the Broncos acquired Jake Plummer, who had been struggling in recent years with Arizona.
After two seasons of mediocrity, the Broncos rebounded with a 10–6 record. They also earned their first playoff berth since 2000. But Denver's season ended with a 41–10 blowout to the Indianapolis Colts in the Wild Card round. Following the season, Clinton Portis was traded to the Washington Redskins, and Shannon Sharpe and Ed McCaffrey both retired.
