Wahidi Bir Ali (Arabic: واحدي بير علي Wāḥidī Bīr ‘Alī), or the Wahidi Sultanate of Bir Ali (Arabic: سلطنة واحدي بير علي Salṭanat al-Wāḥidī Bīr ‘Alī fy), was one of several Wahidi states in the British Aden Protectorate and the Protectorate of South Arabia. Its capital was Bi'r `Ali on the Gulf of Aden coast. The last Sultan, Alawi ibn Salih ibn Ahmad Al Wahidi, was deposed and the state was abolished in 1967 upon the founding of the People's Republic of South Yemen. The area is now part of the Republic of Yemen.
