The cave of Bara-Bahau (or Bara-Bao), a hundred meters long, is one of the Paleolithic decorated caves of the Vézère valley located in the French commune of Le Bugue in Dordogne, region of Nouvelle-Aquitaine.

It is of geological interest, especially for its eccentric concretions, and especially prehistoric, for the wall engravings it contains. It takes its name from an onomatopoeia of local Occitan which means "badaboum" in reference to collapsed blocks visible in the first room. Private property open to the public, it was classified as a historical monument in 1961.

The geological study was entrusted to F.-M. Bergounioux who practiced near the entrance of the cave several soundings, one of which is about twenty meters deep.

The deposits of the two rooms delivered, during developments, rare lithic remains, including Aurignacian-looking blades3.

An animal occupation of the cavity prior to the realization of the engravings is also attested by numerous bones of cave bears (Ursus spelaeus), found on the floor of the second room, and by deep scratches sometimes making it difficult to read the engravings.
