Mosul Eyalet (Arabic: إيالة الموصل; Ottoman Turkish: ایالت موصل, romanized: Eyālet-i Mūṣul) was an eyalet of the Ottoman Empire. Its reported area in the 19th century was 7,832 square miles (20,280 km²). Although the eyalet was overwhelmingly Kurdish, the city of Mosul itself was largely inhabited by Arabs.

Sultan Selim I defeated the army of Shah Ismail at the Battle of Çaldiran, but it wasn't until 1517 that Ottoman armies gained control of Mosul, which remained a frontier garrison city until the 1534 capture of Baghdad. The eyalet was established in 1535. Mosul then became one of three Ottoman administrative territorial units of ‘Irāk. In the 1840s, the Sanjak of Cizre, which before was a part of the Emirate of Bohtan in the Diyarbekir Eyalet, was added to the Mosul Eyalet, which led to an unsuccessful Kurdish revolt against the Ottoman Empire, led by Bedir Khan Beg.
