Dunama Lefiami was the Mai (sultan) of the Kanem–Bornu Empire, located in what is now Nigeria, Cameroon and Chad during the early nineteenth century.
Dunama succeeded his father Ahmad, an old and blind Mai who abdicated after the Fulani Jihad resulted in the capture of Ngazargamu.
Mai Dunama enlisted the support of Muhammad al-Amin al-Kanemi, to counter the Fulani in word and battle.
Dunama rewarded al-Kanemi with slaves and goods, after the defeat of Goni Mukhtar.
In 1809, after Ngazarmu was again captured, the noblemen forced Dubama to abdicate, and Dunama's uncle Muhammad Ngileruma was made Mai.
