Russenorsk (Norwegian pronunciation: [ˈrʉsəˌnɔʂk]; Russian:Руссено́рск, [rʊsʲɪˈnorsk]) is an extinct dual-source pidgin language formerly used in the Arctic, which combined elements of Russian and Norwegian, and which was created by Russian traders and Norwegian fishermen from northern Norway and the Russian Kola peninsula. It was used extensively in Northern Norway for about 150 years in the Pomor trade. Russenorsk is important as a test case for theories concerning pidgin languages since it was used far away from most of the other documented pidgins of the world.
