Kashkar, also known as Kaskar, (Classical Syriac: ܟܫܟܪ), was a city in southern Mesopotamia. Its name appears to originate from Syriac ܟܪܟܐ karḵa meaning "citadel" or "town". Other sources connect it to ܟܫܟܪܘܬܐ kaškarūṯá "farming". It was originally built on the Tigris, across the river from the later medieval city of Wasit. The city was originally a significant Sasanian city built on the west bank of the Tigris where Greek speaking deportees from north-western Syria were settled by Shapur I in the mid third century A.D.
