The Côtes-d'Armor (; in French pronounced as /kot daʁmɔʁ/; Breton: Aodoù-an-Arvor, in Breton pronounced as /ˈoːdu ãn ˈarvor/), formerly known as Côtes-du-Nord until 1990 (Breton: Aodoù-an-Hanternoz|link=no, in Breton pronounced as /ˈoːdu ãn ˌhãntɛrˈnoːs/), is a department in the north of Brittany, in northwestern France. In 2019, it had a population of 600,582.[2]
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.
On February 27, 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 region is an undulating plateau including three well-marked ranges of hills in the south. A granitoid chain, the Monts du Méné, starting in the south-east of the department runs in a north-westerly direction, forming the watershed between the rivers running respectively to the English Channel and the Atlantic Ocean. Towards its western extremity this chain bifurcates to form the Montagnes Noires in the south-west and the Monts d'Arrée in the west of the department. Off the coast, which is steep, rocky and much indented, are the Jentilez, Bréhat and other small islands. The principal bays are those of Saint-Malo and Saint-Brieuc.
The most populous commune is Saint-Brieuc, the prefecture. As of 2019, there are 6 communes with more than 10,000 inhabitants:[2]
| Commune | Population (2019) | |
|---|---|---|
| Saint-Brieuc | 43,605 | |
| Lannion | 20,210 | |
| Lamballe-Armor | 16,688 | |
| Dinan | 14,407 | |
| Plérin | 14,309 | |
| Ploufragan | 11,383 |
The inhabitants of the department are known in French as Costarmoricains.
See also: Departmental Council of Côtes-d'Armor. 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 a region that historically was otherwise strongly Catholic and right-wing. The current president of the departmental council, Christian Coail, is a member of the Socialist Party.

The western part of the department 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.
