John Goulder Campbell (June 25, 1827 – December 22, 1903) was a Scottish-born American businessman and politician. He served one term as Arizona Territory's delegate in the United States House of Representatives and was elected twice, but served only once, to represent Yavapai County in the Council (upper house) of the Arizona Territorial Legislature. Despite his service in the United States Congress, it is unclear as to whether he was ever a United States citizen.
