The Green Bay East–Green Bay West football rivalry is a high school football rivalry between Green Bay East High School and Green Bay West High School, two public high schools in Green Bay, Wisconsin. Played annually since 1905 (other than 1906 and 2020, when the games were cancelled and postponed respectively), it is Wisconsin's longest-running consecutively-played high school football rivalry. The teams first met unofficially in 1895, but did not begin playing annually until ten years later. For much of the early 20th century, the rivalry game was one of the most popular events of the year in Green Bay due to East and West being the only city high schools, drawing crowds that exceeded those of the fledgling Green Bay Packers.
