The Petsamo expeditions (Finnish: Petsamon retket, Swedish: Petsamoexpeditionerna) were two military expeditions in May 1918 and in April 1920 by Finnish civilian volunteers, to annex Petsamo (‹See Tfd›Russian: Pechenga) from Bolshevist Russia. It was one of the many "kinship wars" (Heimosodat) fought by the newly independent Finland during the Russian Civil War. Although both expeditions were unsuccessful, Petsamo was handed over by Russia to Finland in the 1920 Treaty of Tartu.
