Reidar Haaland (21 February 1919 – 17 August 1945) was a police officer and voluntary frontline soldier for the German forces. He hailed from Stavanger. He was a member of Nasjonal Samling from 6 December 1940, and on 20 June 1941 he joined Den Norske Legion. The legion became defunct in 1943, whereupon Haaland found work in Statspolitiet. Already in the autumn of 1943 he was transferred to Gestapo. He became the first Norwegian to receive the death sentence during the post-World War II trials, and was executed on 17 August 1945 at Akershus Fortress, Oslo for treason.
