Abba Poemen the Great (Greek: Ὁ Ἅγιος Ποιμήν; ποιμήν means "shepherd") (c. 340–450) was a Christian monk and early Desert Father who is the most quoted Abba (Father) in the Apophthegmata Patrum (Sayings of the Desert Fathers). Abba Poemen was quoted most often for his gift as a spiritual guide, reflected in the name "Poemen" ("Shepherd"), rather than for his asceticism. He is considered a saint in Eastern Christianity. His feast day is August 27 in the Julian calendar (September 9 in the Gregorian calendar).
