Nieuwe Buitenhaven is the members' marina of WSV De Buitenhaven, a watersports association based in Kampen on the IJssel.

The association manages two harbours: the Nieuwe Buitenhaven serves as the verenigingshaven (members' harbour), while the Oude Buitenhaven is where visiting boats normally moor.

During busy group events at the Oude Buitenhaven, passers-by may use available berths in the Nieuwe Buitenhaven instead. The marina offers good access to a wide range of destinations, including the Kattendiep, Vossenmeer, IJsselmeer, Zwolle, and Lelystad.

Facilities across both harbours include shore power, drinking water, Wi-Fi, a diesel pump, a waste-water station, refuse containers, a chemical toilet disposal point, and a wash-down area. The site is also accessible for wheelchair users.
