He was born at Hurum in Buskerud, Norway. His parents were Nils Steen (1889-1941) and Astrid Karlsen (1899-1986). The father, who died when Reiulf was 7 years old, had been president of the Norwegian Chemical Industry Workers' Union and deputy mayor of the municipality.
Steen was elected leader of the regional Labour Party affiliate at age 14. He had worked in a factory and as a journalist for the newspaper Fremtiden in Drammen before entering politics in 1958. He rose quickly through the ranks of his party, chairing the Workers' Youth League from 1961 to 1964.
He later served as minister of transportation from 1971 to 1972 and minister of commerce and trade from 1979 to 1981. From 1977 to 1993 he was a member of Parliament, representing the constituencies Oslo and Akershus. He was the vice president of the Socialist International from 1978 to 1983 and chaired its committee on Chile from 1975 to 1990. He maintained a long-standing interest in Latin America and was appointed Norwegian ambassador to Chile in 1992, a tenure that lasted until 1996.
He wrote columns for several of the country's leading newspapers, dealing with both national and international issues. He was also active in ATTAC and chaired the Norwegian branch of the European Movement (1999–2001), Norsk Folkehjelp (1999–2003) and the Norwegian branch of the Helsinki Committee for Human Rights (1986–1992). In later years, his memoirs and personal recollections related accounts of his own psychiatric problems and difficulties within the Labour Party.
Reiulf Steen was married twice. In 1960 he married Lis Fridholm (1936-1985). Their marriage was later dissolved. In 1980 he married Inés Vargas. He died on 5 June 2014 and was survived by his wife, four children from his first marriage and step-family. Via his step-daughter, he was father-in-law to Labour politician Raymond Johansen, who was Governing Mayor of Oslo.
