Veh-Ardashir (also spelled as Beh-Ardashir and Weh-Ardashir), was an ancient Sasanian city in present-day Iraq, and formed a suburb of their capital, Ctesiphon.

Originally known as Seleucia, the city was rebuilt and renamed in 230 by the founder of the Sasanian Empire, king Ardashir I (r. 224-240).

The city was known as Mahoza by the Jews, Kokhe (Syriac) by the Christians, and Behrasir by the Arabs.

[2] A governor marzban (general of a frontier province, "margrave") is known to have resided in a fortress in the northern part of this city in ca.

In 636, Veh-Ardashir was captured by the Arab general Khalid ibn Urfuta during the Muslim conquest of Persia.
