Würselen (German pronunciation: [ˈvʏʁzələn] ⓘ, Ripuarian: Wöschele [ˈβœʃələ]) is a town in the borough of Aachen, in North Rhine-Westphalia, Germany.

Würselen lies north of the city of Aachen in the immediate vicinity of the tripoint of Belgium, Germany and the Netherlands.

Its neighbouring settlements are, in clockwise order, the towns of Herzogenrath, Alsdorf and Eschweiler and the city of Aachen.

As part of the administrative reform in North Rhine-Westphalia and the related 1971 Aachen Act, the territory of the borough of Würselen was expanded in 1972 to incorporate the hitherto independent municipalities of Bardenberg and Broichweiden.

The second quarter shows the coat of arms of the Rhine Province, however the bend also represents the river Wurm which flows through the town.
