The Buryats are a Mongolic ethnic group native to southeastern Siberia who speak the Buryat language. They are one of the two largest indigenous groups in Siberia, the other being the Yakuts. The majority of the Buryats today live in their titular homeland, the Republic of Buryatia, a federal subject of Russia which sprawls along the southern coast and partially straddles Lake Baikal. Smaller groups of Buryats also inhabit Ust-Orda Buryat Okrug and the Agin-Buryat Okrug which are to the west and east of Buryatia respectively as well as northeastern Mongolia and Inner Mongolia, China. They traditionally formed the major northern subgroup of the Mongols.

Buryat or Buriat, known in foreign sources as the Bargu-Buryat dialect of Mongolian, and in pre-1956 Soviet sources as Buryat-Mongolian, is a variety of the Mongolic languages spoken by the Buryats and Bargas that is classified either as a language or major dialect group of Mongolian.
