Evagrius of Constantinople

Evagrius (died c. 380) was bishop of Constantinople for brief periods in 370, and possibly 380.

Little is known about Evagrius. In 370, the Arians elected Demophilus to fill the bishopric vacancy after the death of Eudoxius. The Nicene Christians and the deposed bishop of Antioch Eustathius chose Evagrius for that see; but a few months later he was banished by the emperor Valens, and remained in exile until his death.

Some sources claim that he was elected a second time in 379 or 380, after the expulsion of Demophilus by emperor Theodosius I.
