Al-Mansur Salah ad-Din Muhammad ibn Hajji ibn Muhammad ibn Qalawun (1347/48–1398), better known as al-Mansur Muhammad, was the Mamluk sultan in 1361–1363. He ruled in name only, with power held by the Mamluk magnates, particularly Yalbugha al-Umari, al-Mansur Muhammad's regent. The latter had al-Manur Muhammad's predecessor and uncle an-Nasir Hasan killed and al-Mansur Muhammad installed to replace him.
