Kardhiq Castle (Albanian: Kalaja e Kardhiqit) is a ruined hill fortress located in Kardhiq, southern Albania. Built between the late 14th and the early 15th century by the Zenebishi family, it was restored by Ali Pasha in the early 19th century.

The castle is first mentioned in the 1431–32 register of the Sanjak of Albania. The castle has five towers, two of which are of polygonal form and similar to other castles of Ali Pasha. The width of the walls, which feature turrets, is about 1.7 metres (5.6 ft).
