The Urals (Russian: Ура́л) are a geographical region located around the Ural Mountains, between the East European and West Siberian plains. It extends approximately from north to south, from the Arctic Ocean to the bend of Ural River near Orsk city. The boundary between Europe and Asia runs along the eastern side of the Ural Mountains. Ural mostly lies within Russia but also includes a part of northwestern Kazakhstan. This is a historical, not an official entity, with the boundaries overlapping its western Volga and eastern Siberia neighbor regions. At points in time, parts of the Urals were considered a gateway to Siberia, if not Siberia itself, or were combined with the Volga administrative divisions. At present time, there are two official namesake entities, the Ural Federal District and the Ural economic region.
