The 12^th century Château de Biron is a castle in the commune of Biron in the Dordogne département of France. Biron was seized by the Cathars in 1211 and retaken by Simon de Montfort, 5th Earl of Leicester the following year. The Plantagenets held it at times during the 14th and 15th centuries.

The present château bears additions over the centuries that make a picturesque ensemble: a twelfth-century keep, sixteenth-century living quarters, a chapel and vaulted kitchens. The commune purchased the Château de Biron in 1978, with a view to restoring the structure as a tourist draw.

Since 1928, the Château de Biron has been listed as a monument historique by the French Ministry of Culture.
