Fort Chambray or Fort Chambrai (Maltese: Forti Xambrè) is a bastioned fort located in the precincts of Għajnsielem, on the island of Gozo, Malta. It was built in the mid-18th century by the Order of Saint John, in an area known as Ras it-Tafal, between the port of Mġarr and Xatt l-Aħmar. The fort was meant to be the citadel of a new city which was to replace the Cittadella as the island’s capital, but this plan never materialized.

The fort saw use during the French invasion of Malta in 1798, and it was subsequently used as a military hospital and mental institution. The fort is currently being restored and redeveloped as a luxury accommodation.
