Siberian Tatars (Siberian Tatar: сибиртатарлар, себер татарлары, romanized: sibirtatarlar, seber tatarları), or simply Siberians (Siberian Tatar: сибиртар, себерләр, romanized: sibirtar, seberlər), are the indigenous Turkic-speaking population of the forests and steppes of southern Western Siberia, originating in areas stretching from somewhat east of the Ural Mountains to the Yenisey River in Russia. The Siberian Tatars call themselves Yerle Qalıq ("older inhabitants"), to distinguish themselves from more recent Volga Tatar immigrants to the region.

The word "Tatar" or "Tadar" is also a self-designation by some closely related Siberian ethnic groups, namely the Altaians, Chulyms, Khakas, and Shors.
