Despenser's Crusade (or the Bishop of Norwich's Crusade, sometimes just Norwich Crusade) was a military expedition led by the English bishop Henry le Despenser in 1383 that aimed to assist the city of Ghent in its struggle against the supporters of Antipope Clement VII. It took place during the great Papal schism and the Hundred Years' War between England and France. While France supported Clement, whose court was based in Avignon, the English supported Pope Urban VI in Rome.
