Wahidi Habban ( '), or the Wahidi Sultanate of Habban in Hadhramaut ( '), 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. The area is now part of the Republic of Yemen.
The predecessor state, the Wahidi Sultanate (Saltanat al-Wahidiyya), was established at an uncertain date. In 1830 the Wahidi Sultanate split into four states:
On 4 May 1881 Baôl Haf and `Azzan joined. In 1888 the Wahidi Sultanate of Baôl Haf and `Azzan became a British protectorate. In 1895 Biôr `Ali `Amaqin also came under British protection. On 23 Oct 1962 the joint sultanate was renamed Wahidi Sultanate (al-Saltana al-Wahidiyya), while Biôr `Ali and Habban sultanates became subordinate sultanates. On 29 Nov 1967 with the independence of the People's Republic of South Yemen all states were abolished.
The Sultans of the Wahidi Sultanate of Habban had the style of Sultan Habban al-Wahidi.
