Abraham of Ephesus was a 6th-century metropolitan and monk living within the Byzantine Empire. Serving as the Archbishop of Ephesus, he contributed significantly to monasticism by establishing religious houses in both Jerusalem and Constantinople. He is recognized as a saint by both the Roman Catholic and Eastern Orthodox traditions. His written works, specifically two homilies concerning the Annunciation and the Presentation of Jesus, remain valuable historical resources for studying ancient Byzantine liturgical practices.
