The Sanjak of Shahrizor, previously the Sanjak of Baban, later briefly renamed to the Sanjak of Kirkuk, was a second-level administrative division (Sanjak) of the Ottoman Empire, founded in 1534. The name Shahrizor comes from the region of the same name, which likely means "kingly forest". The capital and largest city of the sanjak was Kirkuk. The sanjak was made up of 1,712 Villages across 6 Kazas and 17 Nahiyahs. The Shahrizor Sanjak was initially a sanjak of the Eyalet of Shahrizor, though later it was part of the Mosul vilayet, lying between the Mosul and Sulaymaniyah Sanjak. It was dissolved with the Armistice of Mudros in 1918.
