The Mansudae Assembly Hall (Korean: 만수대의사당) is the seat of the Supreme People's Assembly, the unicameral legislature of North Korea. It is located in the North Korean capital of Pyongyang and sits adjacent to the Korean Revolution Museum. Before the Korean War the territory where the building is situated was the location of the former Pyongyang Women’s Prison.

Facilities include a main meeting hall covering an area of 4,300 square metres (46,000 sq ft) with 2,000 seats for parliament members as well as a simultaneous interpretation system in the hall which has the capacity of translating ten foreign languages at a time. The building is based on Soviet architectural influences with some Korean elements.

On 9 September 2022, a concert was held in the grounds of Mansudae Assembly Hall commemorating the 74th Day of the Foundation of the Republic which was broadcast live on DPRK state television.
