Châteaubriant (; ; Gallo: Châtiaoberiant), is a town in western France, about southwest of Paris, and one of the three sous-préfectures of the Loire-Atlantique department. Châteaubriant is also situated in the historical and cultural region of Brittany, and it is the capital of the Pays de la Mée.
Its inhabitants are called Castelbriantais, and the commune of Châteaubriant proper had 12,022 inhabitants in 2010, while its small metropolitan area numbered 24,125 inhabitants in 2009.
A part of the traditional province of Brittany, Châteaubriant also lies on the threshold of Anjou, and it was an important stronghold in northwestern France during the Middle Ages. The town appeared during the 11th century, around a castle and a priory. A fair, which still exists, was also founded in 1050. Châteaubriant played a certain role during the Mad War between France and Brittany and became a significant cultural centre in the 16th century, when the Renaissance château was built in the medieval fortress.
The town is situated between Nantes and Rennes, and tends to be economically oriented towards the latter. The medieval fair and cattle market are still important for the local economy, but Châteaubriant also developed a metallurgical industry during the 19th century, and then plastics manufacturing during the 20th century.
Châteaubriant is noteworthy for its château, which combines a large medieval castle and a Renaissance palace. The town also has an 11th-century church and a medieval town centre, with half-timbered houses and remains of city walls. During the Second World War, Châteaubriant had a concentration camp, and it is known in France for the 27 hostages who were shot there in 1941.
