The Tatra Mountains (), Tatras (Tatry either in Slovak (pronounced [ˈtatri] ) or in Polish (pronounced [ˈtatrɨ]) - plurale tantum), are a series of mountains within the Western Carpathians that form a natural border between Slovakia and Poland. They are the highest mountains in the Carpathians. The Tatras are distinct from the Low Tatras (Slovak: Nízke Tatry), a separate Slovak mountain range further south.
The Tatra Mountains occupy an area of 785 square kilometres (303 sq mi), of which about 610 square kilometres (236 sq mi) (77.7%) lie within Slovakia and about 175 square kilometres (68 sq mi) (22.3%) within Poland. The highest peak, called Gerlachovský štít, at 2,655 metres (8,711 feet), is located north of Poprad, entirely in Slovakia. The highest point in Poland, Rysy, at 2,500 metres (8,200 ft), is located southeast of Zakopane, on the border with Slovakia.
