Aboubakar Abdel Rahmane (died 1979) was a Chadian warlord active during the civil war.
A semi-literate Muslim Kanembu, he originally belonged to Goukouni Oueddei's People's Armed Forces (FAP).
A member of the FAP's Comité Militaire Interarmées Provisoire (CMIAP), he was expelled in 1977 from the organization for having protested against the neglect of his area, Kanem.
Aboubakar played here an important role, being the only Chadian leader to advocate the withdrawal of French troops from Chad, a key aspect of the following Kano Accord, as the proclaimed necessity of an "African solution" (i.e. Nigerian).
A month later, through Nigerian help he even obtained an associate of his, Lol Mahamat Choua, to be made president of the Transitional Government of National Unity (GUNT).
