Boxing is a combat sport in which two people wearing protective gloves throw punches at each other for a predetermined set of time in a boxing ring.

Knocking a person unconscious or even causing concussion may cause permanent brain damage. There is no clear division between the force required to knock a person out and the force likely to kill a person. Since 1980, more than 200 amateur boxers, professional boxers and Toughman fighters have died due to ring or training injuries. In 1983, editorials in the Journal of the American Medical Association called for a ban on boxing. The editor, Dr. George Lundberg, called boxing an "obscenity" that "should not be sanctioned by any civilized society." Since then, the British, Canadian and Australian Medical Associations have called for bans on boxing.

Professional boxing is forbidden in Iceland, Iran, Saudi Arabia and North Korea. It was banned in Sweden from 1970 until 2007 when the ban was lifted but strict restrictions, including four three-minute rounds for fights, were imposed. It was banned in Albania from 1965 till the fall of Communism in 1991; it is now legal there. Norway legalized professional boxing in December 2014.
