The Nogat is a 62 km long delta branch of the Vistula River in northern Poland. Unlike the main river, it does not empty into Gdańsk Bay but rather into the Vistula Lagoon.
The Nogat has its origin near the village of Biała Góra as a distributary of the Vistula River. Shortly afterwards the river Liwa flows into the Nogat. Then the river passes Malbork and flows north-east towards Elbląg (but does not reach the city). North-west of Elbląg, the Nogat flows into the south-western part of the Vistula Lagoon.
