This is a list of grand masters of the Constantinian Order of Saint George, a dynastic order of knighthood of the Catholic Church. Although it was founded by Albanian nobles claiming descent from the Byzantine Angelos dynasty in the 16th century, the order has throughout its existence maintained that it has its origin in Ancient Roman times, supposedly founded by Constantine the Great in the 4th century. Such an origin is otherwise regarded as being impossible, as there are no Roman or Byzantine records of such an institution ever existing and chivalric orders being completely unknown in the Byzantine world.
