Siyawush (also spelled Siyavash), known in Byzantine sources as Seoses (Σεόσης), was an Iranian officer, who served as the head of the Sasanian army (arteshtaran-salar) during the second reign of the Sasanian king (shah) Kavad I (r. 498–531). In c. 520, he was accused of purposely misusing peace negotiations with the Byzantine Empire, and was thus removed from power and executed.
