Duhnen (toponym derived from dunes) is a seaside resort (Seebad ) along the North Sea, 5 kilometres (3.1 mi) from the centre of Cuxhaven city, Lower Saxony, Germany.

[1] Visitors to Hamburg's nearby island of Neuwerk commonly travel through Duhnen.

It was at one time a remote fishing and farming village, but today is one of the tourist centres of Cuxland.

[2] Horse and trotter racing along Duhnen Beach attracts about 30,000 spectators annually.

The annual event begins when the mud flats, used as the racing track, are exposed by ebbing tides.
