The siege of Amida was a military investment of the Roman fortified frontier city of Amida (modern Diyarbakır, Turkey) by the Sasanian Empire. It took place in AD 359 when the Sasanian army under king Shapur II invaded the eastern provinces of the Roman Empire. Shapur wanted to exploit the absence of the Roman Emperor Constantius II who was overseeing affairs in the western part of the Empire. The city fell, but the strategic gain was little.

Ammianus Marcellinus, a Roman army officer, provided a vivid description of the siege in his work (Res Gestae). Ammianus served on the staff of Ursicinus, the Magister Equitum (master of horse) of the East, during the events of the siege.[7]
