Sepak takraw, or Sepaktakraw, also called buka ball, kick volleyball or foot volleyball, is a team sport. It is played with a ball made of rattan or plastic between two teams of two to four players on a court resembling a badminton court. It is similar to volleyball and footvolley in its use of a rattan ball and players using only their feet, knees, shoulders, chest, and head to touch the ball. Sepak Takraw is often referred to as a mixture of volleyball, for its use of a net, and association football, as players use their feet.

The sport's modern version was introduced, developed, and standardized in 1960 when officials from Malaysia, Singapore, Thailand, and Myanmar met in Kuala Lumpur to agree on a name and standard rules for it. It was previously known as Sepak Raga Jaring and was first exhibited in Penang in 1945. It was introduced in the 1965 Southeast Asian Games in Kuala Lumpur as a medal event. Sepak Takraw is considered Malaysia's national sport.

Sepak takraw is governed internationally by the International Sepaktakraw Federation (ISTAF), formed in 1988, which is responsible for major international tournaments including the ISTAF SuperSeries (ISS) and ISTAF World Cup (IWC), Malaysia's Khir Johari Cup, and Thailand's King Cup.

Sepak takraw resembles native sports known as sepak raga in Malaysia and Indonesia; takraw in Thailand; chinlone in Myanmar; sipa in the Philippines; lataw in Laos; sek dai in Cambodia and cầu mây in Vietnam. It is also claimed to be related to cuju in China, jegichagi in Korea, and kemari in Japan.

The word sepak is Malay (Jawi: سيڨق) for kick while the word takraw is of Thai (Thai: ตะกร้อ) origin, translated as muzzle or woven rattan ball. "Sepak Takraw" literally means "to kick a rattan ball". The choice of this name for the sport was essentially a compromise between Malaysia and Thailand in Kuala Lumpur in 1960.

In the past, it was called "Sepak Raga Jaring" in Malaysia, after the term "Jaring", meaning net in Malay, was added to the traditional "Sepak Raga" game when it was created by Hamid Mydin in Penang in 1945. In Thailand, it is simply known by its original name of "Takraw". Internationally, only the term "Sepak Takraw" is used to refer to the modern sport.

Sepak Takraw may have been introduced to Southeast Asia by the Chinese, who were inspired by the traditional game Cuju, an ancient military exercise where soldiers play to keep a leather ball filled with feathers airborne by kicking it back and forth between two or more people. As the game evolved, the feather-stuffed ball was replaced by an air-filled ball with a two-layered hull. Cuju is also considered by the International Football Association (FIFA) as the origin of football as a sport.

In Myanmar, Sepak Takraw is known as "chinlone". Chinlone has played a prominent role in Myanmar for about 1,500 years. Its style is performance-based because it was first created as a demonstrative activity to entertain Burmese royalty. Chinlone is heavily influenced by traditional Burmese martial arts and dance.
