The Pittsburgh Steelers franchise has had 17 head coaches throughout its history. Founded as the Pittsburgh Pirates in 1933, the name was changed to the Steelers prior to the 1940 season to celebrate the city's heritage of producing steel. Joe Bach served two separate terms as head coach and Walt Kiesling served three separate terms. During the and seasons, due to the number of players who fought in World War II, the Steelers combined their team with Philadelphia and Chicago, respectively. During these seasons, Kiesling shared coaching duties with Greasy Neale and Phil Handler, who have not been included within this list. Since the beginning of the Super Bowl era in 1970, the Steelers have had only four head coaches, the fewest of any NFL franchise.
Struggling with a losing record for much of the franchise's early years, the team's first season with more wins than losses was coached by Jock Sutherland in 1942. In 1947, under Sutherland, the Steelers played their first playoff game against the Philadelphia Eagles. Ten of the 17 head coaches spent their entire professional coaching careers with the franchise, including Kiesling, John McNally, and Chuck Noll, who have also been voted into the Pro Football Hall of Fame. One of only four men to coach the same team for 23 years, Noll retired in 1991. Bill Cowher, who was Noll's replacement, coached the Steelers to their fifth Super Bowl victory in Super Bowl XL (2005) and was voted into the Hall of Fame in 2020. The Steelers' sixth Super Bowl win came in Super Bowl XLIII (2008) under head coach Mike Tomlin, who was hired to replace the retiring Cowher in 2007.
