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.

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.

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.

Unlike other political systems where legislative bodies could nominally pass laws or act as forums for debate, the KPRA was a tool for legitimizing decisions made by the ruling Khmer Rouge.

All major policy decisions were orchestrated by CPK and by the Standing Committee led by Pol Pot, which wielded ultimate power.
