Mansur ibn Muhammad (ar|محمد بن ناصر), (died 1577), was a sultan of the Sultanate of Adal in the Horn of Africa.
After Sultan Muhammad ibn Nasir departed from the city to wage war against the Ethiopian Empire, the Oromos had launched one of the most devastating attacks ever mounted on Harar, a local Harari chronicle states:
Mansur then sent messages to the Somalis to come to the rescue of the city. The Somalis responded quick and favorably. With his new Somali troops Mansur was able to easily repel several Oromo attacks on Harar. He then went to Zeila and Aussa with 150 Somali calvarymen and reestablished control over those areas. However, while in Aussa, Mansur was killed by one of his bodyguards.[1]
