Opposition (32) The Parliament of Wallonia (French: Parlement de Wallonie, pronounced [paʁləmɑ̃ də walɔni]), or the Walloon Parliament (Parlement wallon, [paʁləmɑ̃ walɔ̃]) in the decrees, is the legislative body of Wallonia, one of the three self-governing regions of Belgium (the other two being Flanders and the Brussels-Capital Region).

On the other side of the Meuse, facing the Parliament, is the Élysette, the seat of the Government of Wallonia.

Its members were the national representatives and senators elected in the Walloon Region, who thus by law held two offices simultaneously.

The fourth state reform (1993), transformed Belgium into a federal state and changed the "Walloon Regional Council" (Conseil régional wallon) into the "Council of the Walloon Region" (Conseil de la Région wallonne), which was directly elected for the first time on 21 May 1995.

The federal Chamber of Representatives and the Flemish Parliament both merged theirs into larger province-based constituencies.
