In archaeology, cave paintings are a type of parietal art (which category also includes petroglyphs, or engravings), found on the wall or ceilings of caves. The term usually implies prehistoric origin, and the oldest known are more than 40,000 years old (art of the Upper Paleolithic) and found in the caves in the district of Maros (Sulawesi, Indonesia). The oldest are often constructed from hand stencils and simple geometric shapes. More recently, in 2021, cave art of a pig found in Sulawesi, Indonesia, and dated to over 45,500 years ago, has been reported.

A 2018 study claimed an age of 64,000 years for the oldest examples of non-figurative cave art in the Iberian Peninsula. Represented by three red non-figurative symbols found in the caves of Maltravieso, Ardales and La Pasiega, Spain, these predate the appearance of modern humans in Europe by at least 20,000 years and thus must have been made by Neanderthals rather than modern humans.

In November 2018, scientists reported the discovery of the then-oldest known figurative art painting, over 40,000 (perhaps as old as 52,000) years old, of an unknown animal, in the cave of Lubang Jeriji Saléh on the Indonesian island of Borneo. In December 2019, however, figurative cave paintings depicting pig hunting in the Maros-Pangkep karst in Sulawesi were estimated to be even older, at least 43,900 years old. The finding was noted to be "the oldest pictorial record of storytelling and the earliest figurative artwork in the world".
