The People's Revolutionary Youth Union of Kampuchea was the youth organization of the Khmer People's Revolutionary Party (which governed Kampuchea/Cambodia during the 1980s). The organization was internationally known by its French name, Union de la Jeunesse Populaire Révolutionnaire du Kampuchéa (UJPRK). UJPRK was a member of the World Federation of Democratic Youth.
UJPRK organized youth between the ages of 15 and 26. It functioned as a school for future members of the KPRP. At the time of the 2nd Congress of the UJPRK in 1987, the organization had more than 50,000 members. A significant portion of the members were within the armed forces.
