The Huế massacre (Vietnamese: Thảm sát tại Huế Tết Mậu Thân, or Thảm sát Tết Mậu Thân ở Huế, lit. translation: "Tết Offensive massacre in Huế") was the summary executions and mass murder perpetrated by the Viet Cong (VC) and People's Army of Vietnam (PAVN) during their capture, military occupation and later withdrawal from the city of Huế during the Tet Offensive, considered one of the longest and bloodiest battles of the Vietnam War.

The Battle of Huế began on 31 January 1968 and lasted a total of 26 days. During the months and years that followed, dozens of mass graves were discovered in and around Huế. Victims included women, men, children, and infants. The estimated death toll was between 2,800 and 6,000 civilians and prisoners of war, or 5–10% of the total population of Huế. The Republic of Vietnam (South Vietnam) released a list of 4,062 victims identified as having been either murdered or abducted. Victims were found bound, tortured, and sometimes buried alive. Many victims were also clubbed to death.

A number of U.S. and South Vietnamese authorities as well as a number of journalists who investigated the events took the discoveries, along with other evidence, as proof that a large-scale atrocity had been carried out in and around Huế during its four-week occupation. The killings were perceived as part of a large-scale purge of a whole social stratum, including anyone friendly to American forces in the region. The massacre at Huế came under increasing press scrutiny later, when press reports alleged that South Vietnamese "revenge squads" had also been at work in the aftermath of the battle, searching out and executing citizens that had supported the communist occupation. In 2017, Ben Kiernan described the massacre as "possibly the largest atrocity of the war." Wikipedia
