Wilhelmsburg is a quarter (Stadtteil) of Hamburg, Germany within the borough (Bezirk) of Hamburg-Mitte. It is situated on the homonymous island between the Northern and Southern branches of the Elbe river (Norderelbe and Süderelbe), together with the other quarters of Steinwerder, Veddel and Kleiner Grasbrook. The latter almost exclusively consists of facilities of the port of Hamburg. The four quarters are technically all islands of their own, as they are all separated by their own dams. In 2016 the population was 55,074.
