Gabriel Øidne (11 February 1918 – 4 April 1991) was a Norwegian geographer and historian. Analyzing regional differences in party choice in Norway, he was the first to pinpoint factors relating to relations of production as well as counter-cultural cleavages when describing distinctions between Eastern and Western Norway. He also wrote several works on his native region, Agder, among others on the so-called child migration in older times.
