Jachthaven Het Zwarte Schaar is a small, informal marina situated on an arm of the IJssel, near Doesburg in Gelderland. The waterway has an open connection with the IJssel near Dieren, making it accessible for boats ranging from 2 to 15 meters in length.

Moorings are seasonal, available from April 1 through October 31, and the marina also accommodates transient visitors. The marina is part of the larger Het Zwarte Schaar recreation park, which includes a campsite.

Electrical hook-ups and multiple water taps are available on the docks, while sanitary facilities are shared with the campsite.

A dedicated section of the IJssel arm is reserved for a water-ski course, and a boat ramp serves both transient boaters and camping guests. The surrounding area offers easy access to the Achterhoek region and the Veluwe.
