The Praileaitz Cave (Basque for Rock of the Monk cave) is located in the municipality of Deba (Gipuzkoa, Basque Country).

Early in August 2006, various paleolithic cave paintings were found during an archaeological excavation - a non-figurative iconographic grouping made up of smaller groups of red dots, either isolated or forming a series. Researchers have surmised that the paintings were created c. 18,000 years BP.

The cave also yielded an unusual set of portable art on pebbles, with abstract forms that, in one case, suggested to the researchers resembled the Venus figurines found elsewhere in Paleolithic Europe. It was dated to the Lower Magdalenian period of the Cro-Magnon people.
