Baie de Quiberon

The Baie de Quiberon is an area of sheltered water on the south coast of Brittany. The bay is roughly triangular in shape, open to the south with mainland France to the north-east and the narrow peninsular of Presqu'île de Quiberon providing protection from the Atlantic Ocean to the west. The islands of Belle-Île, Houat and Hœdic add to the bay's protection.

The bay is in the Morbihan département.

In World War II, the area had been identified by military planners as a potential area to disembark military supplies. The plan to achieve this, Operation Chastity, was not executed.
