Boxing is a combat sport in which two people, usually wearing protective gloves and other protective equipment such as hand wraps and mouthguards, throw punches at each other for a predetermined amount of time in a boxing ring.

Amateur boxing is both an Olympic and Commonwealth Games sport and is a standard fixture in most international games—it also has its own World Championships. Boxing is overseen by a referee over a series of one-to-three-minute intervals called rounds.
