Watten (French pronunciation: [wat];[3][4] Dutch: Waten, meaning "ford" as in "river-crossing") is a commune in the Nord department in northern France.

In the 10th century the region around Watten belonged to the Abbey of Saint-Riquier though the counts of Boulogne and Flanders attempted to take possession of it.

[8] Robert II sent them back to his wife Clemence who had them installed in the abbey of Watten in October 1097.

The neighbouring villages are Wattendam (commune of Holque), Millam, Serques, Éperlecques and Wulverdinghe.

Nearby is the Blockhaus d'Éperlecques, a massive German bunker site from World War Two, wrecked by Allied bombing.
