Musa Khan was an Ilkhan from 1336 to 1337 and a grandson of Baydu.

He was installed to the throne of the Ilkhanate by the governor of Baghdad, 'Ali Padsah, on April 12, two days after the latter had defeated Arpa Ke'un in battle. Musa was meant to be a puppet to 'Ali. However, Musa was challenged by the Jalayirid Hasan Buzurg. 'Ali was killed, and Musa was forced to flee after being defeated at Qara Darra on July 24, 1336.
