Cuckmere Haven (also known as the Cuckmere estuary) is an area of flood plains in Sussex, England, where the river Cuckmere meets the English Channel between Eastbourne and Seaford. The river is an example of a meandering river, and contains several oxbow lakes. It is a popular tourist destination with an estimated 350,000 visitors per year, where they can engage in long walks, or water activities on the river. The beach at Cuckmere Haven is next to the famous chalk cliffs, the Seven Sisters.

The wreck of the Polynesia, a German sailing ship that ran aground in April 1890 west of Beachy Head laden with a cargo of sodium nitrate, is exposed at low tide.
