Fennoscandia (Finnish, Swedish and Norwegian: Fennoskandia; Russian: Фенноскандия, romanized: Fennoskandiya), or the Fennoscandian Peninsula, is a peninsula in Europe which includes the Scandinavian and Kola peninsulas, mainland Finland, and Karelia. Administratively, this roughly encompasses the mainlands of Finland, Norway and Sweden, as well as Murmansk Oblast, the Republic of Karelia, and parts of northern Leningrad Oblast in Russia.
Its name comes from the Latin words Fennia (Finland) and Scandia (Scandinavia). The term was first used by the Finnish geologist Wilhelm Ramsay in 1898.
