Limburg (Dutch pronunciation:[ˈlɪmbɵrx]) is a province in Belgium. It is the easternmost of the five Dutch-speaking provinces that together form the Region of Flanders, one of the three main political and cultural sub-divisions of modern Belgium.

Limburg is located west of the river Meuse (Dutch Maas), upon which it borders the similarly named Dutch province Limburg. It also borders on the Wallonian province of Liège to the south, with which it also has historical ties. To the north and west are the old territories of the Duchy of Brabant, the Flemish provinces of Flemish Brabant and Antwerp to the west, and the Dutch province of North Brabant to the north.
