The Columbia Basin of the Pacific Northwest

The Dam Cup is an American college football rivalry in the Pacific Northwest between the Eastern Washington Eagles and the Portland State Vikings. Both are members of the Big Sky Conference in the Football Championship Subdivision of NCAA Division I.

The Dam Cup began in 2010 as a multi-sport competition between the two schools. It refers to the Columbia River watershed and its dams in a double entendre. The EWU campus is upstream in Cheney, southwest of Spokane, while Portland is the major city on the river.

The football teams first played 58 years ago in 1968 and have been conference rivals in the Big Sky since Portland State joined in 1996. They had met 32 times prior to the establishment of the cup; since then, Eastern Washington has won ten of fourteen (.714) to lead the overall series at 23–22–1 (.511).
