Prinses Beatrixhaven is a harbour in Yerseke, Zeeland, situated on the Oosterschelde. It serves a dual purpose, functioning partly as a commercial working harbour and partly as a recreational marina.

The recreational section offers approximately 125 permanent berths, 30 drying berths, and 50 visitor berths, all served by floating pontoons.

Access to Prinses Beatrixhaven is shared with the neighbouring Prins Willem-Alexanderhaven via a single entrance channel, with the division between the two harbours marked roughly at the harbour office.
