The Battle of Xuân Lộc () was the last major battle of the Vietnam War. From the beginning of 1975, People's Army of Vietnam (PAVN) forces swept through the northern provinces of South Vietnam virtually unopposed. In the Central Highlands, South Vietnam's II Corps was completely destroyed, whilst attempting to evacuate to the Mekong Delta region. In the cities of Huế and Da Nang, ARVN units simply dissolved without putting up resistance. The devastating defeats suffered by the Army of the Republic of Vietnam (ARVN) prompted South Vietnam's National Assembly to question President Nguyễn Văn Thiệu's handling of the war, thereby placing him under tremendous pressure to resign.
