Lascaux is a network of caves near the village of Montignac, in the department of Dordogne in southwestern France. Over 600 parietal wall paintings cover the interior walls and ceilings of the cave. The paintings represent primarily large animals, typical local contemporary fauna that correspond with the fossil record of the Upper Paleolithic in the area. They are the combined effort of many generations. With continued debate, the age of the paintings is now usually estimated at around 17,000 years. Because of the outstanding prehistoric art in the cave, Lascaux was inducted into the UNESCO World Heritage List in 1979, as an element of the Prehistoric Sites and Decorated Caves of the Vézère Valley.

In archaeology, cave paintings are a type of parietal art, found on the wall or ceilings of caves. The term usually implies prehistoric origin. These paintings were often created by Homo sapiens, but also Denisovans and Neanderthals; other species in the same Homo genus. Discussion around prehistoric art is important in understanding the history of the Homo sapiens species and how Homo sapiens have come to have unique abstract thoughts. Some point to these prehistoric paintings as possible examples of creativity, spirituality, and sentimental thinking in prehistoric humans.
