Sultan Muhammad Mirza (Persian: محمد میرزا) was a Timurid prince and grandson of the Central Asian conqueror Timur by his third son Miran Shah.

[1] According to Abu'l Fazl, the Grand Vizier of his descendant Akbar, Muhammad Mirza's mother was Mihr Nush of the Fulad Qiya tribe.

[2][note 1] Orientalist Henry Beveridge stated that, while he does not know of this tribe, the fact that Muhammad Mirza is described as always living with his brother Khalil Sultan suggests that the two were likely full-siblings.

[4] This would imply that 'Mihr Nush' was an alternate name for Khalil Sultan's mother Khanzada Begum, the daughter of Aq Sufi Qunqirat of Khwarezm and granddaughter of Jani Beg, Khan of the Golden Horde.

This, along with the fact that he was not mentioned by Clavijo during his 1404 visit to Timur's court, led Henry Beveridge to theorise that Muhammad Mirza had by this point already died, predeceasing his father and grandfather.
