Kašperské Hory ([ˈkaʃpɛrskɛː ˈɦorɪ] ⓘ; German: Bergreichenstein) is a town in Klatovy District in the Plzeň Region of the Czech Republic.

Kašperské Hory consists of nine municipal parts (in brackets population according to the 2021 census):[2] The Kašperk Castle that was built here by Charles IV was named after its founder Karlsberg ("Charles' Mountain" in German) and transcribed to Czech as Kašperk.

The highest point is a contour line on the slopes of the mountain Huťská hora at 1,160 m (3,810 ft) above sea level.

Kašperské Hory existed already at the turn of the 13th and 14th centuries as an extensive mining settlement near an important gold-bearing area.

The Kašperk Castle was built above the town by King Charles IV in 1356 to guard the border and protect the trade route and local gold mines.

[3][4] Declining gold mining was gradually replaced by trade, glassmaking, woodworking, papermaking and cattle breeding.

In the 19th century, Kašperské Hory was the natural regional centre as the seat of offices and schools.
