Wahidi Haban (Arabic: واحدي حبان Wāḥidī Ḥabbān), or the Wahidi Sultanate of Haban (Arabic: سلطنة الواحدي حبان Salṭanat al-Wāḥidī Ḥabbān), was one of several Wahidi states in the British Aden Protectorate. Its capital was Habban. The last sultan, Husayn ibn Abd Allah Al Wahidi, was deposed and the state was abolished in 1967 upon the founding of the People's Republic of South Yemen and the area is now part of the Republic of Yemen.
