The Battle of Thannuris (Tannuris) (or Battle of Mindouos[1]) was fought between the forces of the Eastern Roman Empire under Belisarius and the Persian Sasanian Empire under Xerxes in summer 528, near Dara in northern Mesopotamia.

The attempt to build a new frontier fort at Thannuris/Mindouos by the Byzantines triggered a Sasanian military response. The Byzantines further reinforced the area, but the Sasanian force managed to defeat their superior opponent by stratagem and many Byzantines were killed or captured along with their commanders. The Sasanians demolished the partially-built fort, but their losses were high and they did not advance further.
