The Szelim cave (Hungarian: Szelim-barlang or Szelim-lyuk (Szelim hole), Bánhidai nagy barlang (Bánhidian big cave), Eperjes-barlang, Szemi-luki, Szemi-lyuka, Szelimluk barlang, Bánhidai-zsomboly, Szent Vit-barlang) is located in northwestern Hungary at the western margin of the Gerecse Mountains, 289 m (948 ft) above the Által-ér Valley near Tatabánya city.

The site has been regularly frequented and used as a shelter by local villagers over the centuries, is easily accessible and its huge rectangular entrance features a memorial of the Turul.

The sediments are more than 12 m (39 ft) deep and rich in archaeological finds, that were extracted to the bedrock in a few months in most of the cave.

More recent research results confirm the notion that human occupation in Szelim dates back as far as 200,000 years BP.

Mousterian artefacts and stone tools discovered in the stratae date back to the Upper Paleolithic.
