Noordergat is a yacht marina at Lauwersoog, situated between the Lauwersmeer and the Wadden Sea in the province of Groningen. It serves as a strategic access point for cruising boats, connecting inland Dutch waterways with the Wadden Sea and North Sea.

The Robbengatsluis lock lies roughly 300–350 meters from the marina, providing the passage between the two water systems.

From here, sailors can follow the staande mastroute along the Reitdiep toward the city of Groningen, or head west to reach the Friese meren. Beyond the lock, the Dutch and German Wadden, the Waddeneilanden, and the open North Sea are all within reach.
