Arques (French pronunciation: [aʁk] ⓘ; Languedocien: Arcas) is a commune in the Aude department in the Occitanie region of southern France.

Access to the commune is by the D613 road from Serres in the west passing through the village and continuing to Albières in the east.

[3] The Rialsesse river flows through the centre of the commune and the village from east to west gathering many tributaries.

In the south the Ruisseau de Lait, with many tributaries rising in the commune, flows north-west into the Lac d'Arques (Arques Lake) which feeds the Rialsesse.

[3] [3] The area was owned by the Abbey of Lagrasse in the early 11th century, before coming under the control of the Lords of Termes.
