John II of Cyprus (c. 1418–1458), King of Cyprus and titular King of Jerusalem and Armenia 1432–1458, was the son of Janus. His mother was Charlotte of Bourbon; his sister was Anne de Lusignan, whose 1434 marriage to Louis I of Savoy carried the titular royal styles to the House of Savoy. John II married the Byzantine princess Helena Palaiologina in 1442; their legitimate daughter Charlotte succeeded him. He also fathered an illegitimate son, James, through his mistress Marietta of Patras; James would depose Charlotte in 1464 to become James II of Cyprus.
