Cerizay (French pronunciation: [səʁizɛ]) is a commune in the Deux-Sèvres department in the Nouvelle-Aquitaine region in western France.

The name Cerizay probably originated during the closing centuries of the Roman occupation. During the Middle Ages the old town centre was situated beside a feudal castle. The last two towers of the castle, along with its 12th century chapel, were destroyed when the present (rather flamboyant) church was constructed in 1890.
