Klingenthal is a town in the Vogtland region, in the Free State of Saxony, south-eastern Germany. It is situated directly on the border with the Czech Republic opposite the Czech town of Kraslice, 29 km southeast of Plauen, and 33 km northwest of Karlovy Vary.
The Aschberg towers above the town at 936 m. The extremely elongated town, 10.5 km from end to end, is surrounded by numerous woods of firs.
The town is bisected by the Döbra and Zwota rivers. These two rivers unite at the Czech-German border to form the Svatava river, which in turn flows into the Ohře river at Sokolov.
