Côtes-d'Armor (French pronunciation: ​[kot daʁmɔʁ]; Breton: Aodoù-an-Arvor), formerly known as Côtes-du-Nord, is a department in the north of Brittany, in northwestern France.


Côtes-du-Nord was one of the original 83 departments created on 4 March 1790 following the French Revolution. It was made up from the near entirety of the ancient Pays de Saint-Brieuc, most of historical Trégor, the eastern half of Cornouaille, and the north-western part of the former diocese of Saint-Malo.

In 1990 the name was changed to Côtes-d'Armor: the French word côtes means "coasts" and ar mor is "the sea" in Breton. The name also recalls that of the Roman province of Armorica ("the coastal region").
