In combat sports and hand-to-hand combat, a kick is a physical strike using the foot, leg, or knee (the latter is also known as a knee strike). This type of attack is used frequently, especially in stand-up fighting. Kicks play a significant role in many forms of martial arts, such as Taekwondo, Karate, Pankration, Kung fu, Vovinam, Kickboxing, Muay Thai, Capoeira, Silat, and Kalarippayattu.

The English verb to kick appears only in the late 14th century, apparently as a loan from Old Norse, originally in the sense of a hooved animal delivering strikes with his hind legs; the oldest use is Biblical, in the metaphor of an ox kicking against the pricks.

The act of kicking in general is a universal form of human aggression. The same movement is also used in non-offensive contexts, e.g. a kick to propel an object such as a ball, or a kicking movement without touching anything, e.g. as a dance move.

Kicks as a form of attack are more typically directed against helpless or downed targets, because using a kick in a combat situation bears the significant disadvantage of losing stability of one's stance, as delivering a kick obviously requires lifting at least one foot off the ground.
