Okladnikov Cave, Paleolithic cave in Soloneshensky District, Russia.

Okladnikov Cave is a cave in Siberia with multiple chambers that extend into a hillside. The entrance sits above a river valley and provides access to different archaeological layers inside.

The cave was systematically excavated in the 1980s and reveals the story of early human habitation. Finds show that different animal species and early humans alternately used this space over long periods.

The cave was first named after the nearby village of Sibiryachikha, one kilometre away, and was renamed by Anatoly Derevianko in honour of the archaeologist Alexey Okladnikov. Its stone industry is now called the Sibiryachikha culture, and Levallois-type tools appear here but not at Chagyrskaya Cave.

The cave is not a public attraction: there is no visitor infrastructure, no guided tours and no marked trail. It opens on a Devonian karst escarpment about 14 m above the left bank of the Sibiryachikha, roughly 1 km from the village of Sibiryachikha in Soloneshensky District. The entrance is a south-facing overhang with a stone bench 8 m wide, 2 m high and 4.2 m deep, leading into five narrow galleries that reach about 35 m into the hill. Access is unmarked and best in dry weather; the site lies in the Anuy basin about 50 km north of Denisova Cave.

The cave contains remains of at least 20 different animal species, including creatures no longer found in this region. This diversity shows how different the climate and landscape were during the time it was inhabited.
