Arsenius of Constantinople (Latinised as Arsenius Autoreianus; Greek: Ἀρσένιος Αὐτωρειανός; c. 1200 – 30 September 1273), Ecumenical Patriarch of Constantinople, lived about the middle of the 13th century.

Born in Constantinople c. 1200 and related to previous Patriarch Michael IV of Constantinople, Arsenius received his education in Nicaea at a monastery of which he later became the abbot, though not in orders. Subsequently, he gave himself up to a life of solitary asceticism in a Bithynian monastery and is said to have remained some time in a monastery on Mount Athos.
