His Majesty Sultan Muhammad V (born 6 October 1969) is the 15th and the current Yang di-Pertuan Agong (King) 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 at Istana Batu, Kota Bharu, Kelantan, he was made the Tengku Mahkota (Crown Prince) of Kelantan on 30 March 1979 and formally installed at Balairong Sri, Istana Balai Besar, Kota Bharu, Kelantan on 6 October 1985.

He received his early education at SK Sultan Ismail (1), Kota Bharu, Kelantan, and thereafter at Alice Smith School, Kuala Lumpur. He left for the United Kingdom to study at Oakham School, Rutland, England. He then attended St Cross College, Oxford and the Oxford Centre for Islamic Studies to read diplomatic studies, graduating in 1991. He also studied at Huron University College, London, Ontario, Canada; Deutsche Stiftung für Internationale Entwicklung (DSE), Berlin, Germany; and the European Business School, London, United Kingdom.

In May 2009, his father, Sultan Ismail Petra, suffered a major stroke. Sultan Ismail Petra was admitted to Mount Elizabeth Hospital in Singapore and Tengku Faris was appointed Regent on 25 May in the Sultan's absence. On 16 September 2009, Tengku 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.

Tengku 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, Tengku Faris. In January 2010, the High Court rejected Tengku 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 Tengku Faris in court.

On 13 September 2010, Tengku 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, had petitioned the Federal Court to declare his appointment unconstitutional. Sultan Ismail Petra is still recovering from the stroke he suffered in 2009.

Muhammad V attended the 222nd Meeting of the Conference of Rulers for the first time as a full member in October 2010. This marked the recognition of his accession as Sultan by other rulers.

Sultan Muhammad V was elected Deputy Yang di-Pertuan Agong in October 2011.

He served in that post from 13 December 2011 until his election as Yang di-Pertuan Agong on 13 December 2016.

Sultan Muhammad V was elected by the Conference of Rulers on 14 October 2016 to become the next Yang di-Pertuan Agong, the head of state of Malaysia. His reign began on 13 December 2016, taking over from Abdul Halim, the Sultan of Kedah. Sultan Muhammad V was installed as the fifteenth Yang Di Pertuan Agong of Malaysia on 24 April 2017 in a ceremony held at the Istana Negara, Jalan Duta, Kuala Lumpur. At 47, Sultan Muhammad V is the fourth youngest Yang di-Pertuan Agong to be elected, after Putra of Perlis, Tuanku Mizan Zainal Abidin of Terengganu and Tuanku Abdul Halim of Kedah.

As a divorcee, he is the first Yang di-Pertuan Agong in Malaysian history to reign without a Raja Permaisuri Agong.

His younger brother, Tengku Muhammad Faiz Petra, the Tengku Mahkota, will serve as Regent of Kelantan throughout Sultan Muhammad V's tenure as Yang di-Pertuan Agong.

As Yang di-Pertuan Agong, he holds full responsibility as Commander-in-Chief of the Malaysian Armed Forces. He also holds the full responsibility as the Colonel-in-Chief of the Royal Artillery Regiment, Malaysian Army, and thus attends all its activities and ceremonial occasions.

His Majesty is also the chancellor of MARA University of Technology (UiTM) and National Defence University of Malaysia (UPNM) since 2017.

He has been awarded:
