The Mongolian People's Party (MPP) is a social democratic political party in Mongolia. It was founded as a communist party in 1920 by Mongolian revolutionaries and is the oldest political party in Mongolia. The party played an important role in the Mongolian Revolution of 1921, which was inspired by the Bolsheviks' October Revolution. Following independence, it governed Mongolia as a one-party socialist state. The party changed its name to the Mongolian People's Revolutionary Party (MPRP) and joined the Communist International in 1924 and served as a sole-ruling party of the Mongolian People's Republic.

Mongolia is a landlocked country in East Asia, bordered by Russia to the north and China to the south. It covers an area of 1,564,116 square kilometres, with a population of just 3.3 million, making it the world's most sparsely populated sovereign state. Mongolia is the world's largest landlocked country that does not border a closed sea, and much of its area is covered by grassy steppe, with mountains to the north and west and the Gobi Desert to the south. Ulaanbaatar, the capital and largest city, is home to roughly half of the country's population.
