Cilgerran Castle (Welsh: Castell Cilgerran) is a 13th-century ruined castle located in Cilgerran, near Cardigan. The first castle on the site was thought to have been built by Gerald of Windsor around 1110–1115, and it changed hands several times over the following century between English and Welsh forces. In the hands of William Marshal, 2nd Earl of Pembroke, the construction of the stone castle began after 1223.
After passing through successive families, it was left to ruin and eventually abandoned by 1400. The castle backs onto a cliff face, with the remaining ruins dating from the 13th century. It was most heavily fortified where it faces inland, and includes a pair of drum towers, rather than a central keep, which remain standing. It passed into the hands of the National Trust in 1938, who open it to the public.

Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
