The Parliament of Wallonia is the legislative body of Wallonia, one of the three self-governing regions of Belgium. The parliament building, the former Hospice Saint-Gilles, is situated in Namur, the capital of Wallonia, at the symbolic confluence of the Meuse and the Sambre, the two main rivers of the most inhabited parts of Wallonia, the Sillon industriel. On the other side of the Meuse, facing the Parliament, is the Élysette, the seat of the Government of Wallonia.

Wallonia, officially the Walloon Region, is one of the three regions of Belgium—along with Flanders and Brussels. Covering the southern portion of the country, Wallonia is primarily French-speaking. It accounts for 55% of Belgium's territory, but only a third of its population. The Walloon Region and the French Community of Belgium, which is the political entity responsible for matters related mainly to culture and education, are independent concepts, because the French Community of Belgium encompasses both Wallonia and the bilingual Brussels-Capital Region but not the German-speaking Community of Belgium.
