Limburg (Dutch: Limburg, pronounced [ˈlɪmbʏr(ə)x] ; Limburgish: Limburg [ˈlɪm˦ˌbʏʀ˦əx] or Wes-Limburg [wæsˈlɪm˦ˌbʏʀ˦əx]; French: Limbourg, pronounced [lɛ̃buʁ] ), also known as Belgian Limburg, is a province in Belgium. It is the easternmost of the five Dutch-speaking provinces that together form the Region of Flanders, which is one of the three main political and cultural sub-divisions of modern-day Belgium. As of January 2024, Limburg had a population of 0.9 million.
Limburg is located west of the Meuse (Dutch: Maas), which separates it from the similarly named Dutch province of Limburg. To the south it shares a border with the French-speaking province of Liège, with which it also has historical ties. To the north and west are the old territories of the Duchy of Brabant. Today these are the Flemish provinces of Flemish Brabant and Antwerp to the west, and the Dutch province of North Brabant to the north. Historically Belgian Limburg is roughly equivalent to the Dutch-speaking part of the secular lordship of the medieval Prince-Bishopric of Liège, which was dominated by the County of Loon.
