An honor killing (American English), honour killing (Commonwealth English), or shame killing is a traditional form of murder in which a person is killed by or at the behest of members of their family or their partner, due to culturally sanctioned beliefs that such homicides are necessary as retribution for the perceived dishonoring of the family by the victim. Honor killings are often connected to religion, caste, other forms of hierarchical social stratification, or sexuality. Most often, it involves the murder of a woman or girl by male family members, due to the perpetrators' belief that the victim has brought dishonor or shame upon the family name, reputation or prestige. Honor killings are believed to have originated from tribal customs.
