Heerlen (Dutch pronunciation: [ˈɦeːrlə(n)] ; Limburgish: Heële [ˈɦeə˦lə]) is a city and a municipality in the southeast of the Netherlands. It is the third largest settlement proper in the province of Limburg. Measured as a municipality, it is the fourth largest municipality in the province of Limburg.

Heerlen forms part of the city-region of Parkstad Limburg, an agglomeration with about 250,000 inhabitants and encompassing 8 municipalities. It is to the east of Maastricht and north of the German city of Aachen.

After its early Roman beginnings and a modest medieval period, Heerlen became a centre for the coal mining industry in the Netherlands in the late 19th century. In the 20th century, architect Frits Peutz played a major role in shaping the city as we know it today. His most famous design, and a distinctive building in the city centre, is the so-called Glaspaleis (Glass Palace), listed as one of the world's thousand most architecturally important buildings of the 20th century.
