The Château des Ducs de Joyeuse is a castle in the commune of Couiza in the Aude département of France.
Originally built for the Dukes of Joyeuse in the mid-16th century, the castle is now used as a hotel. The well-preserved building, flanked by round towers, is regarded as typical of many buildings in the Languedoc and Cévennes regions. A pitted rustic work doorway leads to the austere Renaissance courtyard.
It has been listed since 1913 as a monument historique by the French Ministry of Culture.
