Vietnam Airlines Company Limited, trading as Vietnam Airlines (Vietnamese: Hãng Hàng không Quốc gia Việt Nam), is the national flag carrier of Vietnam. Founded in 1956 under the name Vietnam Civil Aviation, the airline was established as a state enterprise in April 1989. Vietnam Airlines is headquartered in Long Bien, Hanoi, with hubs at Noi Bai International Airport and Tan Son Nhat International Airport. The airline flies to 46 destinations in 19 countries, excluding codeshared services.

Vietnam Airlines was officially formed in 1996, after bringing together several service companies. The company is overseen by a seven-seat management board, members of which are appointed by the Vietnamese Prime Minister. Vietnam Airlines was the major stakeholder in Vietnam's second largest carrier, Jetstar Pacific Airlines, but its share has been transferred to the Ministry of Finance, then subsequently, to the State Capital Investment Corporation.

With the core activity of the airline being passenger transportation, Vietnam Airlines also earns revenue from catering and the maintenance and overhauling of aircraft through a number of its subsidiaries. The maintenance and overhauling of aircraft is handled by Vietnam Airlines Engineering Company (VAECO), while the former is performed by Noibai Catering Services Join-Stock Company and Vietnam Air Caterer, who cater airlines that use Vietnam Airlines’ hubs. The airline also controls and operates its cargo division, Vietnam Airlines Cargo, using the airline’s luggage hold on its passenger fleet, as well as a number of dedicated aircraft. Vietnam Airlines owns 100% of Vietnam Air Service Company (VASCO)—a regional airline in southern Vietnam, and 49% of Cambodia Angkor Air—the national flag carrier of Cambodia.
