Isaac the Armenian (Latin: Isachius Armenus; ‹See Tfd›Greek: Ισαάκ, translit. Isaák) was an exarch of Ravenna hailing from the Kamsarakan clan. The chronology of the Exarchate in this period is uncertain: either he succeeded Euselnus and served c. 625 – 643; or he succeeded Eleutherius, and served 620 – 637.
