Finn Gustavsen (22 April 1926 in Drammen – 20 July 2005)[1] was a Norwegian socialist politician active from 1945 to the late 1970s.
He became active in the Norwegian Labour Party youth movement (Arbeidernes Ungdomsfylking) in the fall of 1945 after he earned his university entrance certificate in a year.
The year after, he was hired as a reporter for the regional socialist paper in Vestfold, moved on to the national youth periodical for the Labor Party, then was part of a radical group that formed a foreign affairs journal called Orienteering.
Although most vocal on foreign policy issues related to the arms race and what the editors generally termed "power bloc politics," the magazine became the platform for a left-wing faction within the Labor Party.
In 1961, Gustavsen left the party and formed Sosialistisk Folkeparti and was immediately elected into Storting, the Norwegian Parliament as a representative from Oslo.
