Walloon Brabant (French: Brabant wallon, Dutch: Waals-Brabant (help·info), Walloon: Roman Payis) is a province of Wallonia in Belgium. It borders on (clockwise from the North) the province of Flemish Brabant (Flemish Region) and the provinces of Liège, Namur and Hainaut (Wallonia). Its capital is Wavre. It has an area of 1,093 km² and contains only one administrative district (arrondissement in French), the Arrondissement of Nivelles, with 27 municipalities.
Walloon Brabant was created in 1995 when the former Province of Brabant was split into three parts: two new provinces, Walloon Brabant and Flemish Brabant; and the Brussels Capital Region, which no longer belongs to any province. The split was made to accommodate the federalisation of Belgium in three regions (Flanders, Wallonia and Brussels).
The provincial population was recorded at 347,423 in January 1999, giving a population density of 318 inhabitants / km²

This country is divided in two regions, Flanders and Wallonia (...). Wallonia is divided in (the following provinces...) Tournesis, Flandre wallonne, Haynaut, Namur, Principauté de Liège and Walloon Brabant.

The Université catholique de Louvain is located in this province. A part of the Walloon industrial power was out of the Sillon industriel as the steel industry of Clabecq where there is until now some activities. The Battle of Waterloo also took place in this province, the smallest province of Wallonia.
