Koněprusy Caves (Czech: Koněpruské jeskyně), also Zlatý kůň (Golden Horse), is a cave system in the heart of the limestone region known as Bohemian Karst in the Central Bohemian Region of the Czech Republic. It is located in the municipality of Koněprusy, about 25 kilometres (16 mi) southwest of Prague, 6 km (3.7 mi) south of Beroun. With the length of 2 km (1.2 mi) and vertical range of 70 m (230 ft), it is the largest cave system in Bohemia.

In the earth filled parts of the caves paleontologists have excavated thousands of prehistoric animal bones from the Pleistocene period. Dating back 200,000 to 300,000 years, findings include the remains of the ancestors of the elephant mastodon, sabre-tooth tiger, monkey, cave bear, deer, reindeer, cave lion, woolly rhino, wolf, beaver, hyena and horse amongst others.

The fossilized bones of prehistoric humans aged about 45,000 years (the Zlatý kůň woman), stone tools and decorative objects from the early Stone Age provide evidence that prehistoric man also found refuge in the caves. A counterfeiter's workshop, since dubbed "the Mint", was discovered by pot holers on the upper level of the caves. Here from 1460 to 1470 unknown forgers made the Hussite coins bearing the symbol of the Czech lion. Instead of silver they used copper thinly covered with silver amalgam. The descended underground through a shaft near the top of the Golden Horse hill. It offers panoramic views in all directions; when the weather is fine about one-sixth of Bohemia is visible. The tour of the caves is 620 m (2,034.12 ft) long and lasts about one hour.
