The 1975 Spring Offensive () was a series of increasingly large-scale and ambitious offensive operations by the North Vietnam and the Viet Cong that began on 13 December 1974. The eventual goal of these operations was to defeat the armed forces and force the surrender of the government of the South Vietnam. After the initial success of what was to be a limited campaign in Phuoc Long Province, the North Vietnamese leadership increased the scope of the People's Army of Vietnam's offensive and quickly threatened the Central Highlands city of Buôn Ma Thuột.
