Čertova pec (English: Devil's furnace) is a small karst cave in the Považský Inovec mountains of Slovakia.

As well as being a modern recreational site, the cave is known to have yielded material evidence of repeated human presence and habitation during the Stone Age.

The cave with total length of 27 m (89 ft),[1] is a protected natural monument due to its paleontological significance.

[1] The surrounding area of Certova pec is also a recreational site which includes a motel, a campsite, and a playground.

[4] A radiocarbon date of Szeletian cultural artifacts suggests prehistoric human presence in the cave at around 38,400 years ago.
