WSV IJsselmonde is a volunteer-run yacht club marina situated on the edge of the Rotterdam district of Oud-IJsselmonde, directly on the Nieuwe Maas.

The harbor is accessible from the Nieuwe Maas without passing through any bridge or lock, accommodating yachts with a maximum draft of 2. 20 meters.

With around 200 berths on floating docks and a dedicated visitors' pontoon, it has operated as a recognized Rotterdam sailing destination for more than 90 years.

The marina sits at a turning point on the standing mast route and serves as a convenient midway stop on the Amsterdam–Gouda–Dordrecht–Zeeland corridor.

A fuel station is located across the river near the entrance to the Hollandse IJssel, and a lift crane of up to 25 tonnes is available for urgent repairs.
