The Punkva is a 29 km (18 mi) long river in South Moravia, Czech Republic.

Sloupský potok is the large of the two and enters the underground within the Sloup-Šošuvka cave system near Sloup.

The water reenters the underground thereafter and forms the Punkva Caves, which are a tourist attraction attached to Macocha.

It enters the Svitava on the southern side of Blansko and its flow joins the Danube watershed.
