Braakmanhaven is a seaport in the Dutch province of Zeeland, situated on the seaward side of the Braakman closure dam in Zeeuws-Vlaanderen, with a direct open connection to the Westerschelde.

The harbour was constructed in 1978 and is managed by North Sea Port as part of the broader Terneuzen port area. It lies between the polders De Mosselbanken and Nieuw-Neuzenpolder.

Because it has no locks, vessels with a draught of up to 15 metres can access it directly. Beyond its industrial role, the surrounding area is a popular recreational destination.

The Braakman nature reserve, managed by Staatsbosbeheer, encompasses tranquil wetlands, historic polders, and old forests.

The flat terrain and well-maintained paths make the region well suited for cycling, with the Braakmanboerderij Visitor Center serving as a hub for excursions and information about the reserve.
