Arques (French pronunciation: [aʁk] ⓘ) is a commune in the Pas-de-Calais department in northern France, bordering Saint-Omer.

The town is crossed by the Neufossé Canal, which connects the rivers Aa and Lys.

Arques is between Oudenberg and Boulogne (both Saxon Shore forts) and appears to be land if the sea level is raised 4.5 metres in which case would mean Arques would have been a well protected harbour inland from the town.

It has been the headquarters of Arc International, the largest manufacturer of glassware in the world, since its inception in the 19th century.

[11] La Goudale have relocated to Arques from Douai, to a state of the art brewery which can be visited.
