Talysh Mountains (, Kuh-ha:-ye Ta:lesh) is a mountain range in southeastern Republic of Azerbaijan and northwestern Iran. See Lankaran Lowland for map. The range forms the northwest section of the Elburz Mountains, extending southeastward from the Lankaran Lowland in southeast Azerbaijan to the lower part of the Sefid Rud (White River) in northwest Iran. Few peaks rise above 10,000 ft (3,000 m) and the humid semi-subtropical coastal lowlands along the Caspian Sea, including the Lankaran Lowland, lie at the eastern base of the mountains.
