Záhorie is a region in western Slovakia between the Little Carpathians to the east and the Morava River to the west. Although not an administrative region, it is one of the 21 official tourism regions in Slovakia. Záhorie lies in the area of three administrative regions: Bratislava Region, Trnava Region and Trenčín Region. The region also creates the borders between Slovakia, the Czech Republic and Austria.

The Little Carpathians are a low mountain range, about 100 km long, and 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 is located south of the Devín Gate. The Little Carpathians are bordered by the Záhorie Lowland in the west and the Danubian Lowland in the east.
