Chastellux-sur-Cure ({{IPA|fr|ʃatly syʁ kyʁ}}, literally Chastellux on Cure) is a commune in the Yonne department in Bourgogne-Franche-Comté in north-central France.

The Chateau de Chastellux, the ancestral home of the Chastellux family, is visitable every day after 10{{nbsp}}am except Monday and Tuesday ( tel: 06-76-75-83-71 or 08-86-34-20-03 ). It is still owned by descendants of Marquis de Chastellux who was second in command ( 1780 to 1782) to the Comte de Rochambeau who led the French military contingent during the American War of Independence.
