Ibrahim Muhammadu Macciɗo dan Abu Bakar (1928 - October 29, 2006) was the 19th Sultan of Sokoto (from April 20, 1996, until the time of his death in 2006), the titular ruler of Sokoto in northern Nigeria, and the head of the Nigerian National Supreme Council for Islamic Affairs. As Sultan of Sokoto, he was considered the spiritual leader of Nigeria's 70 million Muslims, roughly 50 percent of the nation's population.
On October 29, 2006, Macciɗo was killed in the crash of ADC Airlines Flight 53, from Abuja to Sokoto along with several top Sokoto State officials and his son, Badamasi Macciɗo, a federal senator.
Macciɗo was the eldest son of the 17th Sultan, Siddiq Abu Bakar dan Usuman, who held the Sultanate for over fifty years. Macciɗo did not succeed his father as Sultan directly. After Ibrahim Dasuki, the 18th Sultan, was arrested and banished by Nigerian military leader Sani Abacha, Macciɗo was appointed Sultan.
