A traditional most sophisticated form of Thai masked drama which combines gracefulness with masculinity in its dancing and singing. It is believed to have been performed since the Ayutthaya Period (1350-1767).

Most khon performances feature episodes from the Ramakien, the Thai version of an Indian epic Ramayana. The Khon roles are male humans, female humans, monkeys and demons. The latter two are dominant ones. Traditionally, all its performers wore masks and all the speaking and singing were done by the reciters and the singers sitting at one side of the stage with the Thai orchestra.
