The Royal ballet of Cambodia (Khmer: ល្ខោនព្រះរាជទ្រព្យ) is a form of performing arts established in the royal courts of Cambodia for the purpose of entertainment as well as ceremonial propitiation. It is the dominant genre of dance theatre in Cambodia that features the classical dance style (របាំក្បាច់បូរាណ) and is analogous to Thai dance theatre of the inner court, the lakhon nai.
It is performed during public occasions and ceremonies in Cambodia as well as among Cambodians in other countries. Performances entails elaborately dressed dancers performing a slow and figurative set of gestures and poses meant to entrance the viewer. The repertoire includes dances of tribute or invocation and the enactment of traditional stories and epic poems such as the Ramayana. The music is played by an ensemble of xylophones, metallophones, woodwind instruments, drums, and gong chimes accompanied by a chorus.
Western names for this dance tradition often make reference to the royal court; including Cambodian court dance as it was performed and maintained by the attendants of the royal palaces. As a performing art, it is formally referred to as the Royal ballet of Cambodia (and as Le ballet royal du Cambodge in French) by UNESCO, Cravath, Brandon, and others in the academic field; although this term may also refer to the royal ballet as a corps, the National Dance Company of Cambodia. The term "Khmer classical dance" is also used alongside "Royal Ballet of Cambodia" in the publications by UNESCO and mentioned authors.
In Khmer, it is formally known as Robam Preah Reach Trop (របាំព្រះរាជទ្រព្យ, lit. dances of royal wealth) or Lakhon Preah Reach Trop (ល្ខោនព្រះរាជទ្រព្យ, lit. theatre of royal wealth). It is also referred to as Lakhon Luong (ល្ខោនហ្លួង, lit. the king's theatre). During the Lon Nol regime of Cambodia, the dance tradition was referred to as Lakhon Kbach Boran Khmer (ល្ខោនក្បាច់បូរាណខ្មែរ, lit. Khmer theatre of the ancient style), a term alienating it from its royal legacy.
