Kickboxing is a full-contact combat sport and a form of boxing based on punching and kicking. The fight takes place in a boxing ring, normally with boxing gloves, mouth guards, shorts, and bare feet to favor the use of kicks. Kickboxing is practiced for self-defense, general fitness, or for competition. Some styles of kickboxing include: Karate, Muay Thai, Japanese kickboxing, Sanda, and Savate.

Although since the dawn of humanity people have faced each other in hand-to-hand combat, the first documentation on the use of kicking and punching in sports combat is from ancient Greece and ancient India. But nevertheless, the term kickboxing originated in Japan, in the 1960s, and developed in the late 1950s from karate mixed with boxing, with Taekwondo, Muay Thai, and Savate also having some influence, with competitions held since then. American kickboxing originated in the 1970s and was brought to prominence in September 1974, when the Professional Karate Association (PKA) held the first World Championships. Historically, kickboxing can be considered a hybrid martial art formed from the combination of elements of various traditional styles. This approach became increasingly popular since the 1970s, and since the 1990s, kickboxing has contributed to the emergence of mixed martial arts via further hybridization with ground fighting techniques from Brazilian jiu-jitsu, and folk wrestling.

There is no single international governing body, although some international governing bodies include the World Association of Kickboxing Organizations (also known as WAKO), World Kickboxing Association, International Sport Karate Association, International Kickboxing Federation, and World Kickboxing Network, among others. Consequently, there is no single kickboxing world championship, and champion titles are issued by individual promotions, such as Glory, K-1 and ONE Championship among others. Bouts organized under different governing bodies apply different rules, such as allowing the use of knees or clinching etc.
