A knockout is a fight-ending, winning criterion in several full-contact combat sports, such as boxing, kickboxing, muay thai, mixed martial arts, karate, some forms of taekwondo and other sports involving striking, as well as fighting-based video games. A full knockout is considered any legal strike or combination thereof that renders an opponent unable to continue fighting.

A heavy blow to the head is a frequent cause of a knockout. Muhammad Ali delivers one to Brian London and retains his heavyweight championship by third-round KO on August 6, 1966.
The referee may stop a match if they deem either competitor unable to fight.
A knockout can be characterized by unconsciousness.
