The Pittsburgh Steelers are a professional American football team based in Pittsburgh, Pennsylvania. They currently belong to the Northern Division of the American Football Conference (AFC) in the National Football League (NFL). The team has appeared in six Super Bowls and is, with the San Francisco 49ers and Dallas Cowboys, one of three teams to have won five of them, and has appeared in thirteen Conference Championship Games, winning six. They are the only team in NFL playoff history to win a Super Bowl after being seeded sixth in the playoffs, winning three consecutive games on the road followed by a Super Bowl victory in Detroit on February 5, 2006.

Originally named the Pittsburgh Pirates the team, along with the Philadelphia Eagles and the now-defunct Cincinnati Reds football team, joined the NFL as 1933 expansion teams, after Art Rooney, Sr. paid a $2,500 fee. The team was renamed the Steelers in 1941 after the city's prominent steel industry to reflect the "blue-collar worker" ethic of the many Pittsburgh fans.
