Capetian House of Anjou
John (; 1354–1360) was a Hungarian royal prince of the Capetian House of Anjou. He was the only son of Stephen of Anjou, Duke of Croatia, Dalmatia and Slavonia, and Margaret of Bavaria. He inherited his father's duchies shortly after his birth. He was regarded the heir to his childless uncle, Louis I of Hungary, who also secured John's right to inherit Poland from Casimir III of Poland. Both Louis I and Casimir III survived John who died prematurely.
