The Ingrians (, ), sometimes called Ingrian Finns, are the Finnish population of Ingria (now the central part of Leningrad Oblast in Russia), descending from Lutheran Finnish immigrants introduced into the area in the 17th century, when Finland and Ingria were both parts of the Swedish Empire. In the forced deportations before and after World War II most of them were relocated to other parts of the Soviet Union. Today the Ingrian Finns constitute the largest part of the Finnish population of the Russian Federation. According to some records, some 25,000 Ingrian Finns have returned or still reside in the Saint Petersburg region.
