Prince Souphanouvong (13 July 1909 – 9 January 1995; Lao: ສຸພານຸວົງ), nicknamed the Red Prince, was along with his half-brother Prince Souvanna Phouma and Prince Boun Oum of Champasak, one of the "Three Princes" who represented respectively the communist (pro-Vietnam), neutralist and royalist political factions in Laos. He was the figurehead President of Laos from December 1975 to August 1991.

Souphanouvong was one of the sons of Prince Bounkhong, the last viceroy 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.
