Saint Anthusa of Mantinea ({{langx|el|Ανθούσα Μαντίνειας}}), also called Anthusa the Confessor was an anchoress and abbess in Constantinople during the 8th century.

Anthusa became an ascetic at a young age, living in the mountains near Constantinople in complete solitude.{{Cite web|title=Venerable Anthusa, Abbess of Mantinea in Asia Minor, and her 90 sisters|url=https://www.oca.org/saints/lives/2014/07/27/102101-venerable-anthusa-abbess-of-mantinea-in-asia-minor-and-her-90-si|access-date=7 July 2020|publisher=Orthodox Church in America}} She later founded two monasteries, one for men and the other for women, and became abbess of the monastery for nuns,{{Cite book|last=Dunbar|first=Agnes B.C.|title=A Dictionary of Saintly Women|publisher=George Bell & Sons|year=1901|volume=1|location=London|pages=76}}{{Cite book|last=Kaplan|first=Michael|title=The Cambridge History of Medieval Monasticism in the Latin West|publisher=Cambridge University Press|year=2020|isbn=978-1108770637|editor-last=Beach|editor-first=Alison I.|location=New York|pages=345|chapter=The Economy of Byzantine Monasteries|editor-last2=Cochelin|editor-first2=Isabelle}} 90 of whom resided there and who "were known for their obedience to their abbess and for their spiritual discipline". She openly defied Emperor Constantine V's iconoclastic prohibitions, so she, her nuns, and her nephew, who was abbot of the second monastery, were arrested and tortured. When Anthusa correctly prophesied that the emperor's wife, who was close to death from childbirth, would safely deliver twins, a boy and a girl, the empress intervened. Anthusa's life was spared, and the empress donated several estates to her. The empress' daughter was named after Anthusa, educated by her, and also became a saint, founding the first orphanage in the Christian world.

Anthusa returned to her monastery, where she lived to old age.{{Cite book|last=Watkins|first=Basil|url=https://books.google.com/books?id=yzqOCgAAQBAJ&q=Amata|title=The Book of Saints: A Comprehensive Biographical Dictionary|publisher=Bloomsbury Publishing|year=2015|isbn=978-0-567-66415-0|edition=8th|location=London}} She died in 759 and was buried in her cell.
