Belgian Lorraine is the part of Lorraine that lies in the south of the Belgian province of Luxembourg, in Wallonia. The term is used solely in a geological context, as the region borders the geologically-distinct Ardennes, to the north.
Culturally and linguistically, Belgian Lorraine is made up of two sub-regions: The Romance-speaking part (in which French dialects are spoken) called Gaume, with Virton as the main cultural city. The Luxembourgish-speaking part called Land of Arlon (in Luxembourgish: Arelerland), with Arlon (Arel) as the main cultural city and the capital of the (Belgian) province of Luxembourg.
