The Albanian Vilayet (, Vilâyet-i Arnavid) was a projected vilayet of the Ottoman Empire in the western Balkan Peninsula, which was to include the four Ottoman vilayets with substantial ethnic Albanian populations: Kosovo Vilayet, Scutari Vilayet, Manastir Vilayet and Janina Vilayet. At times it included the Salonica Vilayet too. The creation of the Vilayet was confirmed in September 1912, but negotiations were interrupted a month later in October with the beginning of the First Balkan War. Plans for an Albanian Vilayet were lost with the Partition of Albania.
