The Bell Game is an annual football contest between two high schools in Pueblo, Colorado, USA: Central High School and Centennial High School. They have been playing each other since 1892 in what is described as the oldest American football rivalry west of the Mississippi River and the largest sports event of its kind in Colorado. The rivalry is sometimes referred to as the "One Hundred Year War". Since the mid-1950s, the teams have played for ownership of the trophy Bell and to paint it their colors and keep it in their school for sporting events and school activities.
