Ambazuces (Greek: Ἀμβαζούκης, romanized: Ambazoukes) was a "Hunnic" ruler in the North Caucasus in the early 6th century, probably of the Sabirs.^[1]

According to the Byzantine historian Procopius, Ambazuces ruled the area of the "Caspian Gates"—most likely referring to the Darial Pass^[1]—during the reign of the Byzantine emperor Anastasius I (r. 491–518).^[2] Procopius reports that he was friendly towards Byzantium, and in his old age offered to cede his realm, but Anastasius declined.^[2] This was probably during or shortly after the Anastasian War of 502–506 between Byzantium and Sassanid Persia.^[1]

After his death, he was succeeded by his sons, who were defeated by the Persian king Kavadh I (r. 488–531), who annexed their territory to Persia.^[2][3]
