This shows the two modern provinces called Limburg next to the medieval duchy they are both named after. The small overlap is Teuven and Remersdaal, in eastern Voeren, a part of modern Belgian Limburg since 1977.

Several different territories have been called Limburg:

Duchy of Limburg (1065–1794), a state in the Holy Roman Empire, today in the Liège Province of Belgium
Province of Limburg (1815–1839) of the United Kingdom of the Netherlands, created from territory outside the former Duchy as King William I did not want the name of Limburg to be lost. It was itself split in 1839 as a consequence of the Belgian Revolution:
- Limburg (Belgium), a province since 1839 in the Flanders region of Belgium
- Limburg (Netherlands), a province since 1839 in the south of the Netherlands
