The Mahmudiyah rape and killings were a series of war crimes committed by five U.S. Army soldiers during the U.S. occupation of Iraq, involving the gang-rape and murder of 14-year-old Iraqi girl Abeer Qassim Hamza al-Janabi and the murder of her family on March 12, 2006. It occurred in the family's house to the southwest of Yusufiyah, a village to the west of the town of Al-Mahmudiyah, Iraq. Other members of al-Janabi's family murdered by American soldiers included her 34-year-old mother Fakhriyah Taha Muhasen, 45-year-old father Qassim Hamza Raheem, and 6-year-old sister Hadeel Qassim Hamza al-Janabi. The two remaining survivors of the family, 9-year-old brother Ahmed and 11-year-old brother Mohammed, were at school during the massacre and orphaned by the event.

In scholarly literature and criminology, gang rape, also called serial gang rape, party rape, group rape, or multiple perpetrator rape, is the rape of a single victim by two or more violators. Gang rapes are forged on shared identity, religion, ethnic group, or race. There are multiple motives for serial gang rapes, such as for sexual entitlement, asserting sexual prowess, war, punishment, and, in up to 30% of cases, for targeting racial minorities, religious minorities, or ethnic groups.
