Justinian (Latin: Iustinianus, Greek: Ἰουστινιανός, after 525–582) was an East Roman (Byzantine) aristocrat and general, and a member of the ruling Justinian dynasty. As a soldier, he had a distinguished career in the Balkans and in the East against Sassanid Persia. In his later years, he plotted unsuccessfully against regent and later emperor Tiberius II (r. 574–582).
