Jachthaven De Batterij is a modern marina situated on the eastern edge of Willemstad, in the Noord-Brabant province of the Netherlands.

It lies adjacent to the Hollands Diep, offering direct access to the inland waterways connecting the major Dutch rivers and the Zeeland waters, including the Volkerak.

The marina offers 215 spacious berths and is sheltered by breakwaters, with an easy entrance suitable for most weather conditions and depths exceeding two metres.

The marina sits within walking distance of Willemstad's historic fortified town centre, whose seven-bastion defensive works date to 1602. Together with the nearby Stadshaven, De Batterij is part of a pair of Blue Flag-certified marinas serving the area.

Vessels transiting between the broader Dutch waterway network will find it a convenient and well-sheltered stopover.
