Siberian Tatars (Siberian Tatar: Сыбырлар; Sibirlar) refers to the indigenous Siberian population of the forests and steppes of South Siberia stretching from somewhat east of the Ural Mountains to the Yenisey river in Russia. The Siberian Tatars call themselves Yerle Qalyq or older inhabitants to distinguish themselves from newer Volga Tatar immigrants to the region.
