The Gulf of Saint-Malo is a part of the south-western English Channel between Brittany, Normandy, and the Channel Islands.
Formed by subsidence and flooding of a continental zone of about 8 500 km2, it extends from the Bréhat archipelago in the west to Guernsey and Alderney in the north and to the west coast of Cotentin (Normandy) in the east.
