Düsseldorf-Hafen is an urban quarter of Düsseldorf, Germany, part of Borough 3, located on the river Rhine and the location of the city's docks. The quarter covers 3.79 km2, and is predominantly commercial and industrial in nature, with a very small residential population. It had 110 residents in the year 2020, making it the Düsseldorf quarter with the lowest population density. The docks prospered for decades but lost much of their trade when Mannesmann closed its nearby pipe factory.
