Stephen (Hungarian: István; 20 August 1332 – 9 August 1354) was a Hungarian royal prince of the Capetian House of Anjou. He was the youngest son of Charles I of Hungary and Elizabeth of Poland to survive childhood. He was styled as duke of Slavonia from 1339 to 1346, but he had no role in the government of the province. Stephen's separate household was set up in 1349. In this year, he received the counties of Szepes and Sáros from his brother, Louis I of Hungary. Louis made him duke of Transylvania in late 1349, but soon appointed him to administer Slavonia.
Stephen was regarded as his childless brother's heir. He and his mother governed the kingdom during Louis's first campaign of Naples in 1350. Late in the same year, Stephen was again made duke of Transylvania, but from 1352 to 1353 he was styled duke of Szepes and Sáros. Thereafter, he was entrusted with the administration of Croatia, Dalmatia and Slavonia. He died on his return from a campaign against Serbia. His infant son, John, inherited his duchy.
