Barneville-Carteret (French pronunciation: [baʁnəvil kaʁtʁɛ]) is a commune in the Manche department in the Normandy region of north-western France.

Sometimes called a "port of the isles", it is located on the right bank of the mouth of the Gerfleur River, at the end of Cape Carteret.

In the street below the town the remains of medieval walls that protected the city and seaside can be visited with a view of Cartaret harbour, the sea, and the Channel Islands.

The resort area spreads into the neighbouring town of Saint-Jean-de-la-Rivière, which was built on an ancient sand dune.

The Cap de Carteret is located at the end of the Armorican Massif and retains traces of the formation with Precambrian deformed granites and metamorphic schist, Cambrian folded arkose from the Variscan orogeny, and shale and armoricain sandstone from the Ordovician period.
