The 2005 season was the New England Patriots' 36th in the National Football League (NFL), their 46th overall and their sixth under head coach Bill Belichick. With a Week 6 loss to the Denver Broncos, the Patriots failed to either improve or match their 14–2 record from last season, finishing with a 10–6 record and the division title before losing in the playoffs to the Broncos, ending their hopes of becoming the first NFL team to three peat in the Super Bowl.
