The Kampuchean People's Representative Assembly (Khmer: សភាតំណាងប្រជាជនកម្ពុជា, Sâphéa Tâmnang Brâchéachôn Kâmpŭchéa) was the official name of the unicameral legislature of Cambodia during the Democratic Kampuchea period.^[1] It was established as the official legislature of Kampuchea on 5 January 1976, consisting of 250 members.

Of the seats, 150 were, due to the constitution, to be reserved for representatives of the peasants, 50 for the "laborers and other working people" and 50 for the Kampuchea Revolutionary Army. All representatives were to be elected simultaneously by secret ballot for five year terms, with the first and only elections taking place on 20 March 1976.

The assembly held its first and only plenary session on 11 to 13 April, appointing the State Presidium, consisting of a president, a first vice president, and a second vice president, as well elected the "administration", the official government of Democratic Kampuchea, and the Standing Committee, due to represent the assembly when not gathered. The members of the KPRA were never elected; the Central Committee of the Communist Party of Kampuchea (CPK) appointed the chairman and other high officials both to it and to the State Praesidium. Plans for elections of members were discussed, but the 250 members of the KPRA were in fact appointed by the upper echelon of the CPK.^[2]

The assembly was effectively abolished when the Vietnamese captured Phnom Penh on 7 January 1979, establishing the People's Republic of Kampuchea.
