The Fifth Down was the name of a college football play that was the result of an error by the crew officiating the game. This play enabled the Colorado Buffaloes to defeat the Missouri Tigers by scoring a touchdown on the last play of their game on October 6, 1990. The ensuing controversy cast doubt on Colorado's claim to Division I-A's 1990 national championship. It has been called one of the top memorable moments and blunders in college football history.

In American football, a team is allowed four attempts or "downs" to move the ball ten 10 yards (9.14 m) towards the goal line. If the offense moves ten yards in four attempts or less, it gains a "first down," which restarts the process. If, after four attempts, the offense has neither scored nor gained ten yards, the other team is given possession of the ball. Under normal circumstances (for example, excluding penalties which can involve replaying a down), no team is supposed to be allowed five attempts. However, due to an officiating error, Colorado was given a fifth down which they used to score the game-winning touchdown as time expired.
