Bohemian Switzerland, also known as Czech Switzerland, is a nature region in the Elbe Sandstone Mountains in the northwestern Czech Republic, protected as a national park.

The Elbe Sandstone Mountains, also called the Elbe Sandstone Highlands, are a mountain range straddling the border between the state of Saxony in southeastern Germany and the North Bohemian region of the Czech Republic, with about three-quarters of the area lying on the German side. In both countries, core parts of the mountain range have been declared a national park. The name derives from the sandstone which was carved by erosion. The river Elbe breaks through the mountain range in a steep and narrow valley.
