Talmont-sur-Gironde is a commune in the Charente-Maritime department in the Poitou-Charentes region in southwestern France. The village lies about 15 km (9.3 mi) south of Royan, on a small promontory which dominates the Gironde Estuary. It appears to be ‘perched’ on this rocky outcrop, in the way that it occupies every square millimetre of space.
Tiny beaches can be found at the base of the fortifications, which mostly are sheer from the sea. Inland there is marshy country and a small waterway runs alongside the south wall of the village. The village is a member of the Les Plus Beaux Villages de France ("The most beautiful villages of France") association.
