Flemish Brabant (Dutch Vlaams-Brabant [ˌvlaːms.ˈbraː.bɑnt] ( listen), French Brabant flamand) is a province of Flanders, one of the three regions of Belgium. It borders on (clockwise from the North) the Belgian provinces of Antwerp, Limburg, Liège, Walloon Brabant, Hainaut and East Flanders. Flemish Brabant also surrounds the Brussels-Capital Region. Its capital is Leuven. It has an area of 2,106 km² which is divided into two administrative districts (arrondissementen in Dutch) containing 65 municipalities.

Flemish Brabant was created in 1995 by the splitting of the former province of Brabant into three parts: two new provinces, Flemish Brabant and Walloon Brabant; and the Brussels-Capital Region, which no longer belongs to any province. The split was made to accommodate the eventual division of Belgium in three regions (Flanders, Wallonia and the Brussels-Capital Region).

It is a province with a rich cultural history and a great diversity of typical products, among them several of the world-famous Belgian beers.
