Upper Yafa or the Sultanate of Upper Yafa, was a state in the British Aden Protectorate and the Protectorate of South Arabia. It was ruled by the Harharah dynasty and its capital was Mahjaba. Within its area were the sheikhdoms of Busi, Dhubi, Hadrami, Maflahi, and Mausatta. In the 1960s, Upper Yafa did not join the British-sponsored Federation of South Arabia but became a part of the Protectorate of South Arabia. It was abolished in 1967 upon the founding of the People's Republic of South Yemen and is now part of the Republic of Yemen.
