The Basra Vilayet (Ottoman language: ولايت بصره‎, Vilâyet-i Basra) was a first-level administrative division (vilayet) of the Ottoman Empire. It historically covered an area stretching from Nasiriyah and Amarah in the north to Kuwait in the south. To the south and the west, there was theoretically no border at all, yet no areas beyond Qatar in the south and the Najd Sanjak in the west were later on included in the administrative system.
