Adurbadagan (Middle Persian: Ādurbādagān/Āδarbāyagān, Parthian: Āturpātākān) was a northwestern province in the Sasanian Empire, mostly overlapping the present-day Azerbaijan region in Iran. Governed by a marzban ("margrave"), it functioned as an important frontier (and later religious) region against the neighbouring country of Armenia. It is also the root word of the modern Iranian "Azerbaijan" region as well as the country of Azerbaijan.
