The Aunus expedition (Finnish: Aunuksen retkikunta; Swedish: Aunus-expeditionen) was an attempt by Finnish volunteers to occupy parts of East Karelia in 1919, during the Russian Civil War. Aunus is the Finnish name for Olonets Karelia. This expedition was one of many Finnic "kinship wars" (heimosodat) fought against forces of Soviet Russia after the Russian Revolution of 1917 and during the Russian Civil War.
