Berge Ragnar Furre (13 April 1937 – 11 January 2016) was a Norwegian historian, theologian and politician for the Socialist Left Party.
Furre was born in Sjernarøy in 1937, the son of engineer Berge Bergesen Furre (1887–1952) and secretary Else Otilie Tjomsaas (1906–1993). He took primary education in Sjernarøy, Stavanger and Oslo, and finished his secondary education in Oslo in 1955. Later that year he enrolled at the University of Oslo. In 1959 he became the leader of the Norwegian Students' Society. He was a member of the Labour Party, but as the chairman of Sosialistisk Studentlag (1956–1957) he was central to the so-called "Easter Uprising" in 1958. He later left the Labour Party to found the Socialist People Party together with other prominent persons in the Easter Uprising, such as Finn Gustavsen. He was the party secretary from 1961 to 1964.
Furre finally graduated with a cand.philol. degree in 1968. Already in 1967 he had been appointed as an editor of the Nynorsk periodical Syn og Segn; he was also a board member of the Nynorsk newspaper Dag og Tid. In 1969 he became a research fellow at NAVF. He left both the editor and research fellow position in 1971 to become an associate professor of history at the University of Tromsø. He was also a member of the board of Noregs Mållag from 1968 to 1969, and vice chairman from 1969 to 1970. From 1971 to 1972 he was a board member of Folkebevegelsen mot EF.
Furre was a member of the Norwegian Parliament for the Socialist Left Party from 1973 to 1977, representing the county Rogaland. During this term he chaired the Standing Committee on Agriculture, and was a member of the Election Committee and the Enlarged Committee on Foreign Affairs. He was the party leader from 1976 to 1983, having formerly been a central committee member in 1961–1964 and 1969–1971 and then deputy leader from 1971 to 1976.
