Joe Jackson Gibbs (born November 25, 1940) is a former American football coach, current NASCAR Championship team owner, and former NHRA team owner. He was the 20th and 26th head coach in the history of the Washington Redskins (1981-1992, 2004-2007). Well known for his long hours and work ethic, Gibbs constructed what Steve Sabol has called, "The most diverse dynasty in NFL history", building championship teams with many players who have had mediocre to average careers while playing for other NFL teams. During his first stint in the National Football League, he coached the Redskins for 12 seasons and led them to eight playoff appearances, four NFC Championship titles, and three Super Bowl titles.

Although Gibbs helped craft a passing-oriented attack during his time in San Diego, his Redskins teams were known to incorporate a smash-mouth, rushing-oriented attack like the counter trey. By building a strong offensive line (known as "The Hogs") Gibbs was able to control the line of scrimmage, allowing workhorse running backs such as John Riggins, George Rogers, and Earnest Byner to power the ground game. Gibbs added a deep passing attack to this which complemented the ground game, utilizing agile receivers such as Art Monk, Gary Clark, and Ricky Sanders. Gibbs' offense was aided during his tenure by aggressive defensive units under the direction of defensive coordinator Richie Petitbon.  Gibbs' system and offensive scheme were robust enough to be successful without a Hall-of-Fame-caliber quarterback at the helm. The Redskins' Super Bowl victories were won featuring Joe Theismann, Doug Williams, and Mark Rypien--capable players who were very successful along with their strong supporting cast.  Gibbs is credited with inventing the single back, double or triple tight end set. He used it to neutralize Hall of Fame linebacker Lawrence Taylor, realizing that to successfully block him with a running back was impossible; an extra tight end and a tackle were required as well. The extra tight end provided additional protection for the quarterback. Gibbs was also credited for creating the Trips formation; stacking three wide receivers to one side. Gibbs incorporated the shifting and motions for which his offenses were known. The formations created mismatches and confusion for the opposing defenses that would then be exploited. He is also one of few coaches that utilized the H-back position prominently in his offense.
