Muaythai at the 2022 World Games – Women's 63.5 kg

The women's 63.5 kg muaythai event at the 2022 World Games was held from 15 to 17 July 2022 at the Boutwell Memorial Auditorium.

Competition format
Like all World Games muaythai events and other martial arts events, the competition is a straight single-elimination tournament. The competition begins with a quarterfinal round, then a semifinal round, and concludes with a gold medal match. Both semifinal losers compete in a bronze medal match.

Bouts consist of three three-minute rounds with a one-minute break between rounds. A Muay Thai practitioner may win by referee stop contest, knockout or by points. Scoring is on the "10-point-must" system, with 5 judges scoring each round. Judges consider "number of muaythai skills and forcefulness of muaythai skills." Each judge determines a winner for each round, who receives 10 points for the round and assigns the round's loser a number of points between 7 and 9 based on the difference of muaythai skills. The judge's scores for each round are added to give a total score for that judge. The Muay Thai practitioner with the higher score from a majority of the judges is the winner.

Competition schedule
All times are in local time (UTC-5), according to the official schedule.
