The Buryat Autonomous Soviet Socialist Republic (Russian: Бурятская Автономная Советская Социалистическая Республика; Buryat: Буряадай Автономито Совет Социалис Республика), abbreviated as Buryat ASSR (Russian: Бурятская АССР; Buryat: Буряадай АССР), was an Autonomous Soviet Socialist Republic of the Russian SFSR of the Soviet Union. In 1923, the republic was created with the name Buryat-Mongol Autonomous Soviet Socialist Republic; its predecessor was the Buryat-Mongol Autonomous Oblast. In 1958, the name "Mongol" was removed from the name of the republic. The Buryat ASSR declared its sovereignty in 1990 and adopted the name Republic of Buryatia in 1992. However, it remained an autonomous republic within the Russian Federation.

In the 1930s, Buryat-Mongolia was one of the sites of Soviet studies aimed to disprove Nazi race theories. Amongst other things, Soviet physicians studied the "endurance and fatigue levels" of Russian, Buryat-Mongol, and Russian-Buryat-Mongol workers to prove that all three groups were equally able.  In 1937, Aga Buryatia and Ust-Orda Buryatia were detached from the Buryat-Mongolian ASSR and merged with Chita and Irkutsk Oblasts, respectively. In 1958, the name "Mongol" was removed from the name of the republic. The Buryat ASSR declared its sovereignty in 1990 and adopted the name Republic of Buryatia in 1992. However, it remained an autonomous republic within the Russian Federation. On 11 July 1995 Buryatia signed a power-sharing agreement with the federal government, granting it autonomy. This agreement would be abolished on 15 February 2002.
