The Denver Broncos are a professional American football team based in Denver, Colorado. They currently belong to the Western Division of the American Football Conference (AFC) in the National Football League (NFL). The Broncos began play in 1960 as a charter member of the American Football League and joined the NFL as part of the AFL-NFL Merger.

The Denver Broncos were a small-market team that met with little success in their early years but have since become one of the elite franchises of the league after having advanced to the Super Bowl six times. In their first four appearances, they suffered successively lopsided defeats, achieving near-legendary status as frustrated losers before winning back-to-back Super Bowl championships in 1998 and 1999 under quarterback John Elway, running back Terrell Davis and coach Mike Shanahan.

For most of their history they played in Mile High Stadium, which became one of the shrines of professional football for its record unbroken string of sell-outs and its legendary home-field advantage (often regarded as the best in the NFL) for the Broncos, especially during the post-season. Mile High Stadium was one of the NFL's loudest stadiums, with steel flooring instead of concrete, which may have given the Broncos an advantage over opponents. Since 2001, they have played at INVESCO Field at Mile High, built next to the former site of Mile High Stadium.
