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").


Côtes-d'Armor is part of the current administrative region of Brittany and is bounded by the departments of Ille-et-Vilaine to the east, Morbihan to the south, and Finistère to the west, and by the English Channel to the north.


The inhabitants of the department are known in French as Costarmoricains.


Côtes-d'Armor's long tradition of anti-clericalism, especially in the interior around Guingamp (a former Communist stronghold), has often led to the department's being seen as an area of left-wing exceptionalism in an otherwise strongly clerical and right-wing Brittany. The current president of the departmental council, Alain Cadec, is nevertheless a member of the centre-right party, Les Républicains.

The western part of the département is part of the traditionally Breton-speaking "Lower Brittany" (Breizh-Izel in Breton). The boundary runs from Plouha to Mûr-de-Bretagne. The Breton language has become an intense issue in many parts of Brittany, and many Breton-speakers advocate for bilingual schools. Gallo is also spoken in the east and is offered as a language in the schools and on the baccalaureat exams.
