Muay Thai literally Thai Boxing and also known as The Art of the Eight Limbs is a form of hard martial art practiced in several Southeast Asian countries including Thailand. It is known as Pradal Serey in Cambodia, Tomoi in Malaysia, Muay Lao in Laos and a similar style called Lethwei in Burma. The different styles of kickboxing in Southeast Asia are analogous to the different types of Kung Fu in China or Silat in the Malay world. The Thai military uses a modified form of Muay Thai called Lerdrit.

Muay Thai has a long history in Thailand and is the country's national sport. Traditional Muay Thai practised today varies significantly from the ancient art Muay Boran and uses kicks and punches in a ring with gloves similar to those used in Western boxing. Muay Thai is referred to as "The Science of Eight Limbs", as the hands, shins, elbows, and knees are all used extensively in this art. A practitioner of Muay Thai ("nak muay") thus has the ability to execute strikes using eight "points of contact," as opposed to "two points" (fists) in Western boxing and "four points" (fists, feet) used in the primarily sport-oriented forms of martial arts.
