The Cambodian People's Party (Khmer: គណបក្សប្រជាជនកម្ពុជា, Kanakpak Pracheachon Kâmpuchéa; CPP), founded as the Kampuchean People's Revolutionary Party (Khmer: គណបក្សប្រជាជនបដិវត្តន៍កម្ពុជា, KPRP), is the current ruling party of Cambodia. It was the sole legal party in the country at the time of the People's Republic of Kampuchea (1979–1989) and during the first two years of the State of Cambodia. Its name was changed during the transitional times of the State of Cambodia, when the single-party system, as well as the Marxist–Leninist ideology were abandoned. Having governed Cambodia since 1979, it is one of the longest-ruling parties in the world. Its main rival is the Cambodia National Rescue Party.
