Nasser-ud-daula Mu'in ad-Din Muhammad Ali Shah (1774[3] – May 7, 1842), was the third King of Oudh from 7 July 1837 to 7 May 1842.

Muhammad Ali Shah was son of Saadat Ali Khan II, brother of Ghazi-ud-Din Haidar Shah and uncle of Nasir-ud-Din Haidar Shah.

[4] He attained the throne with British help following the demise of his nephew, as opposed to the ex-queen mother's (Badshah Begum) attempts to nominate another successor, Munna Jan (the son child of Nasir-ud-Din Haider, whom his father had disavowed).

Padshah Begum and Munna Jan were afterwards imprisoned by the British in the fort of Chunar.

[5] Muhammad Ali Shah of Oudh built the Shrine of Hurr at Karbala.
