The Lambeau Leap is a touchdown celebration in American football in which a player leaps into the bleachers behind the end zone after scoring. The celebration was popularized after Green Bay Packers player LeRoy Butler jumped into the Lambeau Field bleachers after scoring a touchdown from a fumble recovery against the Los Angeles Raiders on December 26, 1993. The celebration has remained popular ever since, even as the National Football League tightened rules on touchdown celebrations in the early 2000s. Some safety concerns have been noted by players and staff, including inappropriate touching by fans and the possibility of an injury to the player leaping into the bleachers. Although uncommon, the celebration has been attempted by multiple players from opposing teams at Lambeau Field. The Lambeau Leap is an important component of the history and traditions of the Packers.

In gridiron football, touchdown celebrations are sometimes performed after the scoring of a touchdown. Individual celebrations have become increasingly complex over time, from simple "spiking" of the football in decades past to the elaborately choreographed displays of the current era.
