The Finnish forest reindeer (Rangifer fennicus fennicus, also known as Eurasian or European forest reindeer is a rare subspecies of the reindeer native to Finland and northwestern Russia. They are found primarily in Russian Karelia and the provinces of North Karelia, Savonia and Kainuu in Finland, though some range into central south Finland. They are distinct from the semi-domesticated mountain reindeer in their larger size, longer legs and preference for dense boreal forest habitat, where they are rarely seen by humans, over the open tundra. The Finnish herd migrates seasonally back and forth across the long Russo-Finnish border.

The mountain reindeer, also called the Norwegian reindeer, northern reindeer, common reindeer or mountain caribou, is a mid-sized to large subspecies of the reindeer that is native to the western Scandinavian Peninsula, particularly Norway. In Norway, it is called fjellrein, villrein or tundra-rein.
