Prince Souphanouvong (July 13, 1909 – January 9, 1995) was the figurehead President of Laos from December 1975 to August 1991.
Souphanouvong was one of the sons of Prince Bounkhong, the last vice-king of Luang Prabang. Unlike his half-brothers, Souvanna Phouma and Phetsarath Ratanavongsa, whose mothers were of royal birth, his mother was a commoner, Mom Kham Ouane.
Nicknamed “The Red Prince”, he became the figurehead leader of the Lao People's Revolutionary Party, and upon its successful seizure of power in 1975, he became the first President of the Lao People's Democratic Republic (and President of the Supreme People's Assembly), a position which he held until 1991.
In 1991, he became an Adviser of Party's Central Committee. Souphanouvong died on 9 January 1995 at the age of 86.
