Sultan Muhammad V (born 6 October 1969) is the 15th and the current Yang di-Pertuan Agong of Malaysia and the Sultan of Kelantan. He was proclaimed Sultan of Kelantan on 13 September 2010, succeeding his father, Sultan Ismail Petra, who was deemed incapacitated by illness. He was proclaimed as Yang di-Pertuan Agong (Supreme Head of the state of Malaysia) on 13 December 2016.

Born Tengku Muhammad Faris Petra ibni Sultan Ismail Petra in Kota Bharu, he was made Crown Prince (Tengku Mahkota) in October 1985. He attended St Cross College, Oxford and the Oxford Centre for Islamic Studies for diplomatic studies, graduating in 1991.

In May 2009, his father, Sultan Ismail Petra, suffered a major stroke. Sultan Ismail Petra was admitted to Mount Elizabeth Hospital in Singapore and Faris was appointed Regent on 25 May in the Sultan's absence. On 16 September 2009, Faris dismissed his younger brother, the Tengku Temenggong of Kelantan, Tengku Muhammad Fakhry Petra, from the Succession Council, which has the power to determine succession to the throne should the Sultan be permanently incapacitated.

Fakhry filed an application at the High Court challenging his dismissal in December, and issued a letter to the state secretary purportedly from the Sultan reversing all actions and decisions made by the Regent, Faris. In January 2010, the High Court rejected Fakhry's application.

In another twist, Sultan Ismail Petra's private secretary "declared" Succession Council chairman Tengku Abdul Aziz Tengku Mohd Hamzah as Regent. The appointment was challenged by Faris in court.

On 13 September 2010, Muhammad Faris Petra was proclaimed the 29th Sultan of Kelantan, in accordance with Article 29A of the State Constitution which states that a Sultan can no longer be king if he is not viable to rule for a period of more than a year. He took the regnal name Muhammad V. However, his father, Sultan Ismail Petra, has petitioned the Federal Court to declare his appointment unconstitutional. Sultan Ismail Petra is still recovering from the stroke he suffered in 2009.
