Papias (Greek: Παπίας) was an Apostolic Father, Bishop of Hierapolis (modern Pamukkale, Turkey), and author who lived circa 70–163 AD. It was Papias who wrote the Exposition of the Sayings of the Lord (Greek: Λογίων Κυριακῶν Ἐξήγησις) in five books.

This work, which is lost apart from brief excerpts of Irenaeus of Lyons (ca. 180 CE) and Eusebius of Caesarea (ca. 320 CE), is an important early source on Christian oral tradition and especially on the origins of the canonical Gospels.
