Samdech Preah Agga Maha Sangharajadhipati Tep Vong (Khmer: សម្ដេចព្រះអគ្គមហាសង្ឃរាជាធិបតី ទេព វង្ស; 12 January 1932 – 26 February 2024) was a Cambodian Buddhist monk who served as the Great Supreme Patriarch of Cambodia until his death in 2024.

[4] Later, during the Vietnamese-sponsored People's Revolutionary Tribunal from 15 to 20 July 1979, Tep Vong accused Pol Pot himself of executing 57 monks, including three of his own nephews.

[5] Tep Vong was subsequently more merciful towards the Khmer Rouge leadership, even comparing Ieng Sary to Aṅgulimāla,[6] the ruthless brigand who completely transforms after a conversion to Buddhism.

Following the 1991 Paris Peace Accords on 23 October, which made former king Norodom Sihanouk head of state, the monkhood was once again divided into Mahanikay and Dhammayut orders.

When, in the turmoil of the 1998 elections, twelve monks close to the opposition locked themselves up in one of the buildings of the temple Wat Ounalom, Tep Vong did not hesitate to request Hun Sen's help to deal with this situation.

[23] In 2002, Tep Vong appointed Tim Sakhorn as an abbot while knowing that the latter was not legitimate, being from Kampuchea Krom and not strictly a Khmer citizen.

On 16 June 2007, Tep Vong was forced to defrock Tim Sakhorn after the latter used his platform to promote nationalist ideology and was accused of immoral conduct, having women in his room.

[26] In 2006, Tep Vong was elevated to the title of Samdech Preah Agga Mahā Sangharājādhipati (Khmer: សម្តេច ព្រះ អគ្គមហាសង្ឃរាជាធិបតី), or Great Supreme Patriarch, placing him at the head of the two orders.

[32] Tep Vong was also given an audience with Pope John Paul II along with Preah Maha Gosananda, becoming one of the international faces of Cambodian Buddhism.

[34] He came into conflict with younger members of the sangha who voiced opposition to government policies and corruption, on one occasion calling publicly for the arrest of the organizers of an anti-government protest.

[35] In one instance, while President of the Unified Sangha, Tep Vong put forth the argument that certain forms of political violence could be condoned by Buddhism.

[37] He also stated that HIV/AIDS is a form of karmic punishment that is best dealt with by cracking down on prostitution, and that monks should not take any role in treating HIV/AIDS patients, nor in disseminating HIV education.
