Wijnendale Castle (French: Château de Wynendaele, Dutch: Kasteel van Wijnendale) is a historic residence in Wijnendale, West Flanders in Belgium which was once a medieval castle. The present buildings largely date to a nineteenth century restoration, though parts of the north wing still date to the fifteenth century. One wing is currently inhabited by the present owners of the castle, while another is open to the public as a museum.
