John II of Jerusalem (died May 20, 1285) was the son of Hugh I of Jerusalem and Isabella of Ibelin. He succeeded his father as King of Cyprus (as John I) and was crowned in Nicosia on May 11, 1284. His succession as king of Jerusalem was opposed by Charles of Anjou, who also opposed the reign of Hugh I (in Cyprus numbered as Hugh III). John died the following year on May 20, having never married and leaving no children. He was buried in the church of St. Demetrius in Nicosia. According to some authors he was poisoned by his brothers, one of whom, Henry II, succeeded him in Cyprus and Jerusalem.
