Weerwaterhaven is a marina situated on the eastern shore of the Weerwater, a small artificial lake in Almere Stad, Flevoland.

The Weerwater itself originated as a borrow pit from excavations for Almere Haven and has since become the central recreational lake of Almere, roughly 600 metres wide with about 7 kilometres of shoreline.

The lake and its surroundings support a range of water-based activities, including a cable ski track to the west and several beaches along the shore.

Divers occasionally access the water from the south shore at Atlantis beach, where a gradual sandy slope descends to a maximum depth of around 9 metres. The marina sits conveniently close to hotels, theatres, and parks in the heart of the city.
