Luxembourg, also called Belgian Luxembourg or West Luxembourg, is the southernmost province of Wallonia within Belgium. It borders the country of Luxembourg to the east, the French departments of Ardennes, Meuse and Meurthe-et-Moselle to the south and southwest, and the Walloon provinces of Namur and Liège to the north. Its capital and largest city is Arlon, in the south-east of the province, near the border of the Grand Duchy of Luxembourg.
It has an area of 4,459 km (1,722 sq mi), making it the largest Belgian province. With around 295,000 residents as of January 2024, Luxembourg is also the least populated province, with a density of 64/km (170/sq mi), making it a relatively sparsely settled part of a very densely populated region, as well as the lowest density in Belgium. It is significantly larger (71%) than, but has less than half the population of, the neighbouring Grand Duchy of Luxembourg. About eighty percent of the province is part of the densely wooded Ardennes region. The southernmost region of the province is called Gaume or Belgian Lorraine (main city: Virton).
