The New York Jets won Super Bowl III.
In a stunning upset, the New York Jets, representing the American Football League (AFL), defeated the heavily favored Baltimore Colts of the National Football League (NFL) by a score of 16-7. This victory, which took place on January 12, 1969, at the Orange Bowl in Miami, is considered a monumental moment in football history as it legitimized the AFL and paved the way for the eventual merger of the two leagues. Led by quarterback Joe Namath, who famously guaranteed a victory before the game, the Jets' triumph is one of the biggest upsets in Super Bowl history.
