Haven Lauwersoog is a working fishing port and marina on the northern coast of the Netherlands, situated at the edge of the small harbor village of Lauwersoog in the Groningen region.

The port accommodates around 150 fishing trawlers and also provides berths for traditional chartered vessels. Its favorable position near the Danish coast and the German Bight has made it a long-established base for fishing boats working those grounds.

The harbor serves as a gateway to the Wadden Sea and Schiermonnikoog Island, with a ferry terminal adjacent to the marina.

It also marks the starting point for walks into the surrounding landscape, including a gentle loop that skirts the Nieuwe Robbengat, a former tidal channel now part of the freshwater Lauwersmeer.

Port facilities include a fish auction, ice plant, fish wholesalers, a floating dry dock, and a customs office.
