Westpoort is a large business park and industrial area encompassing the western part of Amsterdam's harbours (Westelijk Havengebied).
Although Westpoort is the largest business park in the Netherlands, several parts of it are now being developed into residential zones. For now this is limited to the areas encircling the Sloterdijk train station.
Westpoort is an official Amsterdam city borough, but it does not have its own administration or council. The administration of Amsterdam Westpoort is shared between the boroughs Amsterdam-West and Amsterdam Nieuw-West.
