Quintin (French pronunciation: [kɛ̃tɛ̃] ⓘ; Breton: Kintin) is a commune in the Cotes-d'Armor department (Brittany region) in the northwest of France 16 kilometres (9.9 mi) from Saint-Brieuc, the department capital.

Quintin in Roman times was located on a crossroads but significantly developed in the seventeenth and eighteenth centuries, due to the weaving industry and the trade of linen cloth.

Still, the decline came with the French Revolution and cotton gradually taking the lead over linen.

The French Revolution and the wars of religion have left the fabric of the ancient and medieval city devastated.

[3] In 1843, the geographical and historical dictionary of the province of Brittany, by Jean Ogée explains that the denizens of Quintin speak French and Breton.
