The Afanasievo culture, or Afanasevo culture, is an early archaeological culture of south Siberia, occupying the Minusinsk Basin and the Altai Mountains during the eneolithic era, c. 3300 to 2500 BCE. It is named after a nearby mountain, Gora Afanasieva in what is now Bogradsky District, Khakassia, Russia, first excavated by archaeologist Sergei Teploukhov from 1920 to 1929. Afanasievo burials have been found as far as Shatar Chuluu in central Mongolia, confirming a further expansion about 1,500 km beyond the Altai Mountains. The Afanasievo culture is now considered as an integral part of the Prehistory of Western and Central Mongolia.
