Collective punishment is a punishment or sanction imposed on a group for acts allegedly perpetrated by a member of that group, which could be an ethnic or political group, or just the family, friends and neighbors of the perpetrator. Because individuals who are not responsible for the acts are targeted, collective punishment is not compatible with the basic principle of individual responsibility. The punished group may often have no direct association with the perpetrator other than living in the same area and can not be assumed to exercise control over the perpetrator's actions. Collective punishment is prohibited by treaty in both international and non-international armed conflicts, more specifically Common Article 33 of the Fourth Geneva Convention and Article 4 of the Additional Protocol II.

The Geneva Convention relative to the Protection of Civilian Persons in Time of War, more commonly referred to as the Fourth Geneva Convention and abbreviated as GCIV, is one of the four treaties of the Geneva Conventions. It was adopted in August 1949, and came into force in October 1950. While the first three conventions dealt with combatants, the Fourth Geneva Convention was the first to deal with humanitarian protections for civilians in a war zone. There are currently 196 countries party to the 1949 Geneva Conventions, including this and the other three treaties.
