Ang Snguon (prince)
Ang Snguon (, 1794–1822) was a Cambodian prince. He was the third son of King Ang Eng. The Siamese king Rama I died in 1809. King Ang Chan II refused to attend his royal cremation. Instead, Ang Chan sent three Cambodian princes, including Ang Snguon, Ang Em and Ang Duong, to attend the funeral. Ang Snguon and Ang Em were appointed Cambodian "Uprayorach" Rama II's action obviously polarised the Cambodian court into pro-Siamese and pro-Vietnamese factions. After the envoy returned to Cambodia, Ang Chan had Phraya Chakri and Phraya Kalahom executed. Ang Snguon, Ang Em  and Ang Duong escaped from Oudong secretly with hundred followers, they fled to Pursat and sought aid from Siamese. In response, a Siamese army marched to Cambodia in 1811. The Cambodian defectors were placed in Battambang. With the help of Siamese army, Snguon demanded Ang Chan to granted three districts to him, but was rejected. Snguon's forces marched to seize Sambour, Kampong Chhnang and Oudong. When the news reached Phnom Penh, Ang Chan was taken to Saigon by Vietnamese. Ang Snguon was appointed the regent. Vietnam sent a large army to restore Ang Chan. When the news reached Bangkok , Rama II ordered Ang Snguon, Ang Em and Ang Duong to take their followers to Bangkok. Snguon died of illness in Bangkok in 1822.
