The South Vietnam Air Force (Vietnamese: Không lực Việt Nam Cộng hòa – KLVNCH), officially the Republic of Vietnam Air Force (sometimes Vietnam Air Force – VNAF) was the aerial branch of the Republic of Vietnam Military Forces, the official military of the Republic of Vietnam (South Vietnam) from 1955 to 1975.

The VNAF began with a few hand-picked men chosen to fly alongside French pilots during the State of Vietnam era. It eventually grew into the world's sixth largest air force at the height of its power, in 1974. It is an often neglected chapter of the history of the Vietnam War as they operated in the shadow of the United States Air Force. It was dissolved in 1975 after the Fall of Saigon; many of its members emigrated to the United States.

In March 1949, Emperor Bảo Đại officially requested that the French help set up a Vietnamese military air arm. Pressure was maintained with the assistance of Lt. Col. Nguyễn Văn Hinh, who had flown the B-26 Marauder with the French Air Force in the Second World War. In March 1952, a training school was set up at Nha Trang, and the following year two army co-operation squadrons began missions flying the Morane-Saulnier MS.500 Criquet light aircraft. In 1954, the French allocated a number of Dassault MD.315 Flamant armed light transports to the inventory of this Vietnamese air arm. Vietnamese pilot trainees began to be sent to France for more advanced training. In May 1954, with the fall of Điện Biên Phủ, the position of France changed, and on January 31, 1955, the Vietnam Air Force (VNAF) was inaugurated. French instructors for pilots and mechanics remained until late 1956, and transferred 69 F8F Bearcat aircraft to the VNAF, which throughout the late 1950s were the main strike aircraft.
