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 and is accessible to vessels drawing up to approximately 2.

1 metres. It offers around 400 berths ranging from 7 to 15 metres in length, and transient visitors can typically find a berth in boxes not occupied by permanent holders.

Centrally positioned within the Dutch Delta, Herkingen makes a practical base for exploring the Grevelingenmeer and the surrounding waterways.

Despite its modern facilities, the harbour retains a relaxed, quiet atmosphere well suited to cruising sailors and motorboaters alike.
