The 2021 season was the Denver Broncos' 52nd season in the National Football League (NFL) and the 62nd overall. It was also the final season under the ownership of Pat Bowlen's estate who owned the team since the 1984 season.

2021 marked the first season since 2011 in which John Elway did not serve as general manager, as he relinquished those duties shortly after the end of the 2020 season. Elway remained part of the Broncos' personnel, as the president of football operations, and led the hiring of new general manager George Paton.

The Broncos started 3–0, albeit against teams who would combine for a 11–40 record (New York Giants, Jacksonville Jaguars and New York Jets), but after that, the Broncos' performance was memorably bad, going 4–10 the rest of the way, including losing their last four games. The Broncos' slightly improved on their 5–11 record from 2020, but missed the playoffs for a sixth consecutive season and suffered their fifth consecutive losing season (both the second-longest streaks in franchise history) following a loss to the Los Angeles Chargers in Week 17. Linebacker Von Miller, the Broncos' franchise record-holder for the most career sacks, was traded to the Los Angeles Rams at mid-season.

Statistically, the Broncos' ranked third in scoring defense, and their defense also ranked within the top 10 in total yards and passing yards. However, their offense ranked in the bottom 10 in points scored, scoring 30+ points only twice and failing to reach 20 points in 9 of their 17 games, resulting in the firing of head coach Vic Fangio after three seasons.

Coaching changes

February 4: Chris Cook was hired as an offensive quality control coach. February 8: Christian Parker was hired as a defensive backs coach. He spent the previous two seasons with the Green Bay Packers as a defensive quality control coach. Parker replaces Renaldo Hill, who departed on January 25 to become the Los Angeles Chargers' defensive coordinator.

Front office changes January 3: During halftime of the Broncos' 2020 regular season finale, director of player personnel Matt Russell announced his retirement, after eight seasons in that role. January 4: John Elway announced that he will remain president of football operations, but will relinquish his general manager duties, and led the hiring of a new general manager. January 13: George Paton was hired as the new Broncos' general manager. Paton spent the previous 14 seasons in the Minnesota Vikings' front office, including the previous nine seasons as the Vikings' assistant general manager and the last three as vice president of player personnel. May 21: Darren Mougey was promoted to be Paton's right-hand man, director of player personnel.
