Muhammadu Attahiru II (Arabic: محمد الطاهر الثاني) was the thirteenth Sultan of the Sokoto Caliphate from 1903 to 1915. Attahiru II was the great grandson of Usman dan Fodio, the founder of the Sokoto Caliphate and son of Ali Babba bin Bello, the fourth Sultan. Upon the death of the eleventh sultan Abderrahman dan Abi Bakar in 1902, Attahiru II was the primary challenger to the candidacy of Muhammadu Attahiru I, with the later being selected as the Sultan. After losing this selection to Attahiru I, it is claimed that Attahiru II became largely uninterested in the affairs of the Caliphate.
