The prime minister of Myanmar is the head of government of Myanmar. The post was re-established in 2021 by the State Administration Council (SAC), the country's ruling military junta, to lead its nominally-civilian provisional government. The provisional government is subject to the decision-making of the SAC; additionally, there is significant overlap in the membership of both bodies. There is no provision for a prime minister in the 2008 Constitution of Myanmar, with the president being the constitutional head of government. The current prime minister is Min Aung Hlaing, who is also the leader of the junta and the Commander-in-Chief of Defence Services. The post had been used by previous military governments, as recently as 2011.

The Provisional Government of the Republic of the Union of Myanmar, is the executive body of Myanmar under the current military junta, the State Administration Council. On 1 August 2021, it replaced the Management Committee of the State Administration Council, which had been in place since 19 February 2021, following the 2021 Myanmar coup d'état. Some ministers were appointed by Min Aung Hlaing immediately following the coup on 1 February, in his capacity as Commander-in-Chief of Defence Services exercising emergency powers.
