Ypres (; ; , ) is a Belgian municipality located in the Flemish province of West Flanders. Though Ieper is the Dutch and only official name, the city's French name, Ypres, is most commonly used in English due to its role in World War I when only French was in official use in Belgian documents, including on maps. The municipality comprises the city of Ypres and the villages of Boezinge, Brielen, Dikkebus, Elverdinge, Hollebeke, Sint-Jan, Vlamertinge, Voormezele, Zillebeke, and Zuidschote. Together, they are home to some 34,900 inhabitants.
