The People's Consultative Assembly of the Republic of Indonesia is the legislative branch in Indonesia's political system. It is composed of the members of the House of Representatives (DPR) and the Regional Representative Council (DPD). Before 2004, and the amendments to the 1945 Constitution, the MPR was the highest governing body in Indonesia.

The politics of Indonesia take place in the framework of a presidential representative democratic republic whereby the President of Indonesia is both head of state and head of government and of a multi-party system. Executive power is exercised by the government. Legislative power is vested in both the government and the bicameral People's Consultative Assembly. The judiciary is independent of the executive and the legislature.
