Peter (Hungarian: Péter; died 1218) was a Hungarian prelate at the turn of the 12th and 13th centuries, who served as Bishop of Győr from 1205 to 1218. Prior to that, he was chancellor in the royal court of Emeric, King of Hungary between 1202 and 1204. He participated in the Fifth Crusade, where he was killed in fights against the Ayyubid Sultanate. Some historians identify him with the chronicler Anonymus, author of the Gesta Hungarorum.
