Taekwondo (also spelled Tae Kwon Do, Taekwon-Do, or Taegwondo) is the most popular of the Korean martial arts and is the Korean national sport. It is also one of the world's most commonly practiced martial arts and an Olympic sport.

In Korean, derived from hanja, Tae means "to kick or destroy with the foot"; Kwon means "to punch with the fist"; and Do means "way" or "art". Hence, Taekwondo is loosely translated as "the art of hand and foot" or "the way of the foot and the fist." Taekwondo's popularity has resulted in the divergent evolution of the art. As with many other martial arts, Taekwondo is a combination of combat technique, self-defense, sport, exercise, entertainment, and philosophy.
