The Mongolian People's Republic was a unitary sovereign socialist state which existed between 1924 and 1992, coterminous with the present-day country of Mongolia in East Asia. It was ruled by the Mongolian People's Revolutionary Party and maintained close links with the Soviet Union throughout its history.

Geographically, it was bordered by China to its south and the Soviet Union to its north. Until 1944, it also bordered the Tuvan People's Republic, another Soviet satellite state recognized only by Mongolia and the Soviet Union.

The Mongolian People's Republic was proclaimed on November 26, 1924. The government took control of the Bogda Khan's seal after his death according to the 26 November 1924 Constitution of the Mongolian People's Republic.
