Châteauroux (French pronunciation: [ʃa.to.ru]) is the capital of the Indre department in central France and the second-largest town in the province of Berry, after Bourges.

Its residents are called Castelroussins.

Châteauroux lies on the Indre River 250 km south of Paris and 142 km south of Orléans. It is situated on the edge of the government-owned Châteauroux forest and the Brenne national park. The city boasts 450 hectares (1112 acres) of parks, amounting to 52 m² (560 sq ft) for each resident. Châteauroux's average elevation is 154 m above sea level.

Châteauroux enjoys a mild climate. Temperature extremes range from an average January low of 0.8 °C (33 °F) to an average August high of 25.1 °C (77 °F).

The old town, close to the river, forms a nucleus around which a newer and more extensive quarter, bordered by boulevards, has grown up; the suburbs of St. Christophe and Déols lie on the right bank of the Indre. The castle from which the city takes its name was built in the latter part of the 10th century by Raoul, prince of Déols. During the Middle Ages it was the seat of a seigniory, which was raised to the rank of countship in 1497. In 1616, when it was held by Henry II, prince of Condé, it was raised to the rank of duchy. In 1736 it returned to the crown, and was given to Marie Anne de Mailly-Nesle, duchess of Châteauroux, by Louis XV in 1744. The present Château Raoul housing the préfecture offices dates from the 15th century.
