The Royal Palace (Khmer: ព្រះបរមរាជាវាំងនៃរាជាណាចក្រកម្ពុជា, Preah Barum Reachea Veang Nei Preah Reacheanachak Kampuchea), in Phnom Penh, Cambodia, is a complex of buildings which serves as the royal residence of the king of Cambodia. Its full name in the Khmer language is Preah Barum Reachea Veang Chaktomuk Serei Mongkol (Khmer: ព្រះបរមរាជវាំងចតុមុខសិរីមង្គល). The Kings of Cambodia have occupied it since it was built in 1860's, with a period of absence when the country came into turmoil during and after the reign of the Khmer Rouge.
The palace was constructed after King Norodom relocated the royal capital from Oudong to Phnom Penh in the mid-19th century. It was gradually built atop an old citadel called Banteay Kev. It faces towards the East and is situated at the Western bank of the cross division of the Tonle Sap River and the Mekong River called Chaktomuk (an allusion to Brahma).
