The Little Carpathians (also: Lesser Carpathians, Slovak: Malé Karpaty; German: Kleine Karpaten; Hungarian: Kis-Kárpátok) are a low, about 100 km long, mountain range, part of the Carpathian Mountains. The mountains are situated in Western Slovakia, covering the area from Bratislava to Nové Mesto nad Váhom, and northeastern Austria, where a very small part called Hundsheimer Berge (or Hainburger Berge) is located south of the Devín Gate. The Little Carpathians are bordered by Záhorie Lowland in the west and the Danubian Lowland in the east.

In 1976, the Little Carpathians were declared a protected area under the name Little Carpathians Protected Landscape Area, covering 646.1 km² (249.5 sq mi). The area is rich in flora and fauna diversity and contains numerous castles, most notably the Bratislava Castle, and caves. Driny is the only cave open to the public. The three highest mountains are Záruby at 768 m (2,520 ft), Vysoká at 754 m (2,474 ft), and Vápenná at 752 m (2,467 ft).
