The Tatra Mountains (pronounced (help·info)), Tatras, or Tatra (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 m (8710 ft), is located north of Poprad, entirely in Slovakia. The highest point in Poland, Rysy, at 2,499 m (8200 ft), is located south of Zakopane, on the border with Slovakia.[1][2]
