Säkkijärven polkka ("the Säkkijärvi polka"), also called the "Karelian-Finnish Polka," is a well-known folk tune from Finland, popular with Finnish accordionists to the extent that it can be called their national anthem. It was especially popularized by Viljo "Vili" Vesterinen (1907–1961). The tune was first recorded in Säkkijärvi (now Kondratyevo in the Leningrad Oblast, Russia), and the words sometimes sung to the tune point out that Säkkijärvi itself might have been lost, but that Finns could at least keep the polka.
