Julian Cesarini the Elder (It.: "Giuliano Cesarini, seniore") (1398 in Rome – November 10, 1444 in Varna, Bulgaria) was one of the group of brilliant cardinals created by Pope Martin V on the conclusion of the Western Schism. His intellect and diplomacy made him a powerful agent first of the Council of Basel and then, after he broke with the Conciliar movement at Basel, of Papal superiority against the Conciliar movement. The French bishop Bossuet described Cesarini as the strongest bulwark that the Catholics could oppose to the Greeks in the Council of Florence.
