The Battle of Ban Me Thuot was a decisive battle of the Vietnam War which led to the complete destruction of South Vietnam's II Corps Tactical Zone. The battle was part of a larger North Vietnamese military operation known as Campaign 275 to capture the Tay Nguyen region, known in the West as the Vietnamese Central Highlands.

In March 1975 the People's Army of Vietnam (PAVN) 4th Corps staged a large-scale offensive, known as Campaign 275, with the aim of capturing the Central Highlands from the Army of the Republic of Vietnam (ARVN) in order to kick-start the first stage of the 1975 Spring Offensive. Within ten days, the North Vietnamese destroyed most ARVN military formations in II Corps Tactical Zone, exposing the severe weaknesses of the South Vietnamese military. For South Vietnam, the defeat at Ban Me Thuot and the disastrous evacuation from the Central Highlands came about as a result of two major mistakes. Firstly, in the days leading up to the assault on Ban Me Thuot, ARVN Major General Phm Vn Ph repeatedly ignored intelligence which showed the presence of several PAVN divisions around the district. Secondly, President Nguyn Vn Thiu's strategy to withdraw from the Central Highlands was poorly planned and implemented.In the end, it was the ordinary South Vietnamese soldiers and their families who paid the ultimate price, as North Vietnamese artillery destroyed much of the South Vietnamese military convoy on Route 7.

The 1975 spring offensive (Vietnamese: chiến dịch mùa Xuân 1975), officially known as the general offensive and uprising of spring 1975 (Vietnamese: Tổng tiến công và nổi dậy mùa Xuân 1975) was the final North Vietnamese campaign in the Vietnam War that led to the capitulation of Republic of Vietnam. After the initial success capturing Phước Long Province, the North Vietnamese leadership increased the scope of the People's Army of Vietnam's (PAVN) offensive and captured and held the key Central Highlands city of Buôn Ma Thuột between 10 and 18 March. These operations were intended to be preparatory to launching a general offensive in 1976.

Following the attack on Buôn Ma Thuôt, the Republic of Vietnam realized they were no longer able to defend the entire country and ordered a strategic withdrawal from the Central Highlands. The retreat from the Central Highlands, however, was a debacle as civilian refugees fled under fire with soldiers, mostly along a single highway reaching from the highlands to the coast. This situation was exacerbated by confusing orders, lack of command and control, and a well-led and aggressive enemy, which led to the utter rout and destruction of the bulk of South Vietnamese forces in the Central Highlands. A similar collapse occurred in the northern provinces.

Surprised by the rapidity of the ARVN collapse, North Vietnam transferred the bulk of its northern forces more than 350 miles (560 km) to the south in order to capture the South Vietnamese capital of Saigon in time to celebrate their late President Ho Chi Minh's birthday and end the war. South Vietnamese forces regrouped around the capital and defended the key transportation hubs at Phan Rang and Xuân Lộc, but a loss of political and military will to continue the fight became ever more manifest. Under political pressure, South Vietnamese President Nguyễn Văn Thiệu resigned on 21 April, in hopes that a new leader that was more amenable to the North Vietnamese could reopen negotiations with them. It was, however, too late. Southwest of Saigon IV Corps, meanwhile, remained relatively stable with its forces aggressively preventing VC units from taking over any provincial capitals. With PAVN spearheads already entering Saigon, the South Vietnamese government, then under the leadership of Dương Văn Minh, capitulated on 30 April 1975.
