John (died 1238–41) was the Lord of Caesarea from 1229 and an important figure in the kingdoms of Cyprus and Jerusalem. He was the only son of Walter III of Caesarea and Marguerite d'Ibelin, daughter of Balian of Ibelin. He was often called "the young lord of Caesarea" throughout his life to distinguish him from his father, who had been called "the old lord of Caesarea".
