The Huế Massacre (Vietnamese: Thảm sát tại Huế Tết Mậu Thân or Vietnamese: thảm sát Tết Mậu Thân ở Huế) is the name given to the summary executions and mass killings perpetrated by the Viet Cong and North Vietnamese Army during their capture, 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.
