Lauwersgat is a small marina located on the northeastern section of the Nieuwe Robbengat, a waterway within the Lauwersmeer that lies southwest of Lauwersoog.

The harbor sits beside a camping area along the Strandweg and is part of the broader Beleef Lauwersoog recreational complex.

It caters primarily to permanent berth holders, with a limited number of spaces available for visiting boats staying several days or longer.

The Nieuwe Robbengat itself originated as a tidal channel, cut off from the open sea when the Lauwerszee was dammed and subsequently connected to the Vaarwater naar Oostmahorn.

The northeastern stretch where Lauwersgat is found is open to both cargo and pleasure craft, and shares the area with two other marinas as well as beaches along the lakeshore that are popular for swimming in summer.
