The Mal'ta–Buret' culture is an archaeological culture of the Upper Paleolithic (c. 24,000 to 15,000 BP) on the upper Angara River in the area west of Lake Baikal in the Irkutsk Oblast, Siberia, Russian Federation. The type sites are named for the villages of Mal'ta (Мальта), Usolsky District and Buret' (Буреть), Bokhansky District (both in Irkutsk Oblast).
A boy whose remains were found near Mal'ta is usually known by the abbreviation MA-1 (or MA1). According to research published since 2013, MA-1 belonged to a population related to the genetic ancestors of Siberians, American Indians, and Bronze Age Yamnaya people of the Eurasian steppe. In particular MA-1 was found to be genetically close to modern-day Native Americans, Kets, Mansi, Nganasans and Yukaghirs.
