The Ural (Russian:Урал, pronounced [ʊˈrɑl]) or Jayıq/Zhayyq (Bashkir: Яйыҡ pronounced [jɑˈjɯ̞q ], Kazakh:Жайық, pronounced [ʒɑjə́q]), known as Yaik (Russian:Яик) before 1775, is a river flowing through Russia and Kazakhstan in Eurasia. It originates in the southern Ural Mountains and ends at the Caspian Sea. At 2,428 kilometres (1,509 mi), it is the third-longest river in Europe after the Volga and the Danube, and the 18th-longest river in Asia. The Ural River is conventionally considered the boundary between the continents of Europe and Asia.
