The 2006 season was the Denver Broncos' 37th in the National Football League (NFL) and their 47th overall. Following a 7–2 start, the team collapsed down the stretch as the team failed to improve on their 13–3 record from 2005 and they finished the season with a 9–7 record, missing the playoffs for the first time since 2002, due to a 23–26 overtime loss to the San Francisco 49ers and allowing the Kansas City Chiefs to win the tiebreaker, by beating the Jacksonville Jaguars 35–30.
