Dilbeek (Dutch pronunciation: [ˈdɪlbeːk] ) is a municipality in the province of Flemish Brabant, in the Flemish region of Belgium. The municipality comprises the villages of Dilbeek proper, Groot-Bijgaarden, Itterbeek (with Sint-Anna-Pede), Schepdaal (with Sint-Gertrudis-Pede), Sint-Martens-Bodegem, and Sint-Ulriks-Kapelle. Dilbeek is located just outside the Brussels-Capital Region (and is part of the city's urban sprawl, contiguous with Berchem-Sainte-Agathe, Moortebeek (Anderlecht) and Molenbeek-Saint-Jean) in the Pajottenland, hence the local name Poort van het Pajottenland (Gate to the Pajottenland).
Even though Dilbeek is located in the Dutch-language area of Belgium, there is a French-speaking minority represented by 3 members on the 35-seat local council. It is a mostly residential community with some preserved rural areas and some industrial zones. The Brussels Ring road (R0, part of E19) bisects the municipality, with a major junction with the A10 motorway (part of E40) located within its boundaries.
