The Dominican Civil War (Spanish: Guerra Civil Dominicana), also known as the April Revolution (Spanish: Revolución de Abril), took place between April 24 and September 3, 1965, in Santo Domingo, Dominican Republic. It started when civilian and military supporters of the overthrown democratically elected president Juan Bosch ousted the militarily-installed president Donald Reid Cabral from office. The second coup prompted General Elías Wessin y Wessin to organize elements of the military loyal to the dictator Reid ("loyalists") and launch an armed campaign against the "constitutionalist" rebels.

Allegations of communist support for the rebels led to a United States invasion (codenamed Operation Power Pack), which later became an Organization of American States occupation of the country by the Inter-American Peace Force. Although ostensibly neutral, U.S. civilian and military leaders deployed troops in a way that aided the anti-Bosch forces.

In 1966, Bosch lost the presidential election to Joaquín Balaguer. Foreign troops left later that year.
