The Château de Bressuire is a ruined castle in the town of Bressuire in the Deux-Sèvres département of France. The site has been inhabited continuously since the Celtic epoch. The castle was built on the site of an oppidum of the Gauls and was first documented in 1029, in a charter at Saint-Cyprien de Poitiers. It belonged to the Beaumont-Bressuire family until the start of the 16th century. The castle was acquired by the commune in 1975. It has been listed since 1996 as a monument historique by the French Ministry of Culture.
