Kun Khmer competitions at the 2023 SEA Games took place at Morodok Techo National Stadium, Phnom Penh. Kun Khmer or Pradal serey is an ancient Cambodian variation of Kick boxing, dating back to the Khmer Empire in the 9th century AD. A total of 19 medals were awarded. 
The sport marked its debut at the SEA Games, however a similar sport named Muay Thai was contested in earlier editions. Thai athletes protested over the use of the term 'Kun Khmer' over 'Muay Thai'. The International Federation of Muaythai Associations boycotted the events and Thai athletes decided not to take part in the games under the name 'Kun Khmer'.
