The Longues-sur-Mer battery (German: Marineküstenbatterie (MKB) Longues-sur-Mer; also designated Widerstandsnest (Wn) 48)^[1] is a World War II German coastal artillery battery approximately 1 km (0.62 mi) north of the village of Longues-sur-Mer in Normandy, France. The battery is sited on a 60 m (200 ft) cliff overlooking the Baie de Seine and formed a part of Germany's Atlantic Wall coastal fortifications, between the Allied landing sectors of Gold Beach and Omaha Beach.

The battery shelled Allied naval forces off both beaches on D-Day (6 June 1944), but was damaged by Allied shore bombardment the same day, then captured on 7 June 1944 by British ground forces, playing no further part in the Normandy campaign.

The battery is the only one in Normandy to retain several of its original guns in situ. It was listed as a historical monument in October 2001, and remains in a good state of conservation.
