The Aurignacian (/ɔːrɪɡˈneɪʃən/) is an archaeological industry of the Upper Paleolithic associated with Early European modern humans (EEMH) lasting from 43,000 to 26,000 years ago. The Upper Paleolithic developed in Europe some time after the Levant, where the Emiran period and the Ahmarian period form the first periods of the Upper Paleolithic, corresponding to the first stages of the expansion of Homo sapiens out of Africa. They then migrated to Europe and created the first European culture of modern humans, the Aurignacian.

The Proto-Aurignacian and the Early Aurignacian stages are dated between about 43,000 and 37,000 years ago. The Aurignacian proper lasted from about 37,000 to 33,000 years ago. A Late Aurignacian phase transitional with the Gravettian dates to about 33,000 to 26,000 years ago. The type site is the Cave of Aurignac, Haute-Garonne, south-west France. The main preceding period is the Mousterian of the Neanderthals.

One of the oldest examples of figurative art, the Venus of Hohle Fels, comes from the Aurignacian or Proto-Gravettian and is dated to between 40,000 and 35,000 years ago (though earlier figurative art may now be known, such as at the Lubang Jeriji Saléh site in Indonesia). It was discovered in September 2008 in a cave at Schelklingen in Baden-Württemberg in western Germany. The German Lion-man figure is given a similar date range.

A Levantine Aurignacian culture is known from the Levant, with a type of blade technology very similar to the European Aurignacian, following chronologically the Emiran and Early Ahmarian in the same area of the Near East, and also closely related to them. The Levantine Aurignacian may have preceded European Aurignacian, but there is a possibility that the Levantine Aurignacian was rather the result of reverse influence from the European Aurignacian; this remains unsettled.

The Aurignacians are part of the wave of anatomically modern humans thought to have spread from Africa through the Near East into Paleolithic Europe, and became known as European early modern humans, or Cro-Magnons. This wave of anatomically modern humans includes fossils of the Ahmarian, Bohunician, Aurignacian, Gravettian, Solutrean and Magdalenian cultures, extending throughout the Last Glacial Maximum (LGM), covering the period of roughly 48,000 to 15,000 years ago. In terms of population, the Aurignacian cultural complex is chronologically associated with the human remains of Goyet Q116-1, while the subsequent eastern Gravettian is associated with the Vestonice cluster.

The Aurignacian tool industry is characterized by worked bone or antler points with grooves cut in the bottom. Their flint tools include fine blades and bladelets struck from prepared cores rather than using crude flakes. The people of this culture also produced some of the earliest known cave art, such as the animal engravings at Trois Freres and the paintings at Chauvet cave in southern France. They also made pendants, bracelets, and ivory beads, as well as three-dimensional figurines. Perforated rods, thought to be spear throwers or shaft wrenches, also are found at their sites.

Aurignacian figurines have been found depicting faunal representations of the time period associated with now-extinct mammals, including mammoths, rhinoceros, and tarpan, along with anthropomorphized depictions that may be interpreted as some of the earliest evidence of religion.

Many 35,000-year-old animal figurines were discovered in the Vogelherd Cave in Germany. One of the horses, amongst six tiny mammoth and horse ivory figures found previously at Vogelherd, was sculpted as skillfully as any piece found throughout the Upper Paleolithic. The production of ivory beads for body ornamentation was also important during the Aurignacian. The famous paintings in Chauvet cave date from this period.
