Wormhout (French pronunciation: [wɔʁmut]; before 1975: Wormhoudt; West Flemish: Wormout) is a commune in the Nord department in northern France.

[3] Several people in Wormhout still speak West Flemish, a local dialect of Dutch and the traditional language of the region, while French-speakers form a majority, due to centuries of French political and cultural influence.

('Flanders' and the communes of Thourotte, Crépy-en-Valois, Bollezeele, Feignies, Flines-lez-Raches and Wormhout use the same arms.)

Wormhout is twinned with the resort town of Llandudno, Conwy, Wales.
