Herkingen Marina is a modern yacht harbour situated on the northeastern shore of the Grevelingenmeer, on the island of Goeree-Overflakkee in South Holland.

The marina is reached via a narrow channel accessible to vessels with a maximum draft of approximately 2. 1 metres. The harbour offers around 400 berths ranging from 7 to 15 metres in length.

Visiting boats are typically accommodated in berths temporarily vacated by permanent residents, meaning spaces for passers-by are generally available.

Despite its modern facilities, the marina retains a relaxed, quiet atmosphere well suited to exploring the Grevelingenmeer and the surrounding Delta region.
