The prime minister of Mongolia is the head of the Government of Mongolia, which is the highest executive body in Mongolia. The office was de jure established in 1912, shortly after the Bogd Khanate of Mongolia declared its independence from the Qing dynasty during the Mongolian Revolution of 1911. Sain Noyon Khan Tögs-Ochiryn Namnansüren was the first officeholder, serving from 1912 until his death in 1919. After the outbreak of the Russian Civil War and Namnansüren's death, Mongolia was reoccupied by the Republic of China in mid 1919.
Da Lama Gonchigjalzangiin Badamdorj was installed as puppet prime minister by warlord Xu Shuzheng, serving until the abolition of Outer Mongolian autonomy in January 1920. Later in February 2021, the Bogd Khanate was restored by White Russian forces led by Roman von Ungern-Sternberg. A rival Red Army-backed People's Provisional Government, with Dambyn Chagdarjav as acting head, was established by the Mongolian People's Party in March 1921. In the aftermath of the People's Revolution of 1921, the Bogd Khan was allowed to remain as a constitutional monarch until his death in 1924. From 1911 to 1924, five men served as prime ministers during the Bogd Khanate.
The Mongolian People's Republic was subsequently established in 1924, ending the theocratic rule entirely. From 1924 to 1992, during the Mongolian People's Republic, the official title of the head of government underwent several changes, namely:
Throughout 68-year long socialist period, a total of 10 men served as the head of government of the Mongolian People's Republic. Since the adoption of the current Constitution of Mongolia in 1992, 17 men have served as prime minister from 1992 to 2026. The current officeholder is Nyam-Osoryn Uchral, who was appointed on 30 March 2025 by the State Great Khural, the unicameral parliament of Mongolia.
The longest-serving prime minister in Mongolian history was Marshal Yumjaagiin Tsedenbal, who led from 1952 until 1974; the longest-serving prime minister of modern Mongolia was Luvsannamsrain Oyun-Erdene, who held the position from 2021 to 2025. The shortest-serving officeholder was Jalkhanz Khutagt Sodnomyn Damdinbazar, who served for only 2 months in 1921, while the shortest-serving prime minister of modern Mongolia was Janlavyn Narantsatsralt, who served for 225 days from 1998 to 1999.
