TheSupreme Patriarch of Cambodia (Khmer:សម្ដេចព្រះសង្ឃរាជ;Pali:Sangharāja, is thede facto leader ofBuddhism in Cambodia.

The titles for the Cambodian Supreme Patriarchs are derived fromPali. The full official title of the Supreme Patriarch of the Maha Nikaya isSamdech Preah Sumedhādhipati (Khmer:សម្តេច ព្រះ សុមេធាធិបតី);sumedhādhipati means 'wise lord'. In letters with King-FatherNorodom Sihanouk, the following title is used for the Great Supreme Patriarch Tep Vong:Samdech Preah Agga Mahā Sangharājādhipati (Khmer:សម្តេច ព្រះ អគ្គមហាសង្ឃរាជាធិបតី); which is translated as 'foremost great supreme patriarch leader'.^[1]

The full official title of the Supreme Patriarch of the Dhammayuttika Nikaya isSamdech Preah Aphiserei Sukonthea Mohasangreacheathipadei (Abhisirī Sugandhā Mahāsangharājādhipati) (Khmer:សម្តេច ព្រះ អភិសិរី សុគន្ធា មហាសង្ឃរាជាធិបតី). This title means 'Of Higher Merit and Pure Virtue, Great Supreme Patriarch Leader'. In letters with King-Father Sihanouk, an abbreviated title is used in the valediction:Samdech Preah Sangreach (Khmer:សម្តេច ព្រះ សង្ឃរាជ).'^[1]

Between 1855 and 1981, there were two Supreme Patriarchs in the Kingdom of Cambodia: one for the Cambodian branch of the ThaiDhammayuttika Nikaya order, and one for theMaha Nikaya. In 1981, under the supervision of the Vietnamese-backedPeople's Republic of Kampuchea, VenerableTep Vong was elected Supreme Patriarch of a new, unifiedsangha modelled on theVietnamese Theravada Buddhist Sangha Congregation.^[2]

After the signing of theParis Peace Accords in 1991,KingNorodom Sihanouk appointed VenerableBour Kry as Supreme Patriarch of Dhammayuttika Nikaya.^[3] Today, the two orders are each headed by their own patriarch, unlike inThailand where only oneSupreme Patriarch heads both orders. TheConstitution of Cambodia provides a seat on theRoyal Council of the Throne to both Supreme Patriarchs, thus giving each a say in the selection of the Cambodian sovereign.

In 2006, Tep Vong was elevated to the status ofGreat Supreme Patriarch,^[4] while Venerable Non Nget was subsequently elevated to Supreme Patriarch of the Maha Nikaya. Tep Vong is the first monk in 150 years to bear the title of Great Supreme Patriarch.^[4]
