Côte d’Argent (French: [kot d‿aʁ.ʒɑ̃]; lit. 'Silver Coast') is a name given to part of the Atlantic coast of the Aquitaine region in France.

The term was first coined to describe the Aquitaine coast in 1905 by the journalist and poet Maurice Martin. The Congrès national des sociétés de géographie officially approved the name in 1907. The region it referred to eventually shrunk; the northern part including Royan became the Côte de Beauté and the southern part including Anglet became the Basque Coast.^[1]

In the south-west of France, facing the Atlantic Ocean, La Côte d’Argent is part of the Bay of Biscay. It is limited at its north by the Gironde mouth and at its south by the river Adour. Large waves make this a popular surfing destination and create some of the largest sand dunes in Europe, including the Dune of Pilat.^[2][3] Surfing competitions include the Quiksilver Pro France and the Lacanau Pro.
