Stephen VIII Báthory (Hungarian: Báthory István, pronounced [ˈbaːtori ˈiʃtvaːn]) (1477–1534) was a Hungarian noble. He was a son of Nicholas Báthory (1462–1500) of the Somlyó branch of the Báthory family, and of Sophia Bánffy de Losoncz. He was appointed in 1521 adjoin (deputy) of the Voivode of Transylvania, and served under the Voivode John Zápolya. After the Battle of Mohács in 1526, Stephen supported Zápolya's claim to the Kingship of Hungary and in 1529 was made Voivode of Transylvania. He fathered eight children with his wife Catherine Telegdi.
