Bach Mai Airfield (Vietnamese: Sân bay Bach Mai) is a disused military airport in Thanh Xuan District, Hanoi, Vietnam, located along modern-day Le Trong Tan street.

It is now the site of the Vietnam People's Air Force Museum, where a number of period military aircraft are on display.

In 1939 the unit was redesignated le Groupe Mixte Aérien 595 formed of L'escadrille d'observation 1/595 with the Potez 25 and an escadrille de chasse 2/595 with the Morane-Saulnier M.S.406.

Following the Japanese Invasion of French Indochina in September 1940 the remaining aircraft were formed into the Groupement Aérien Nord Indochine, but this was dissolved in March 1943 due to wear and tear and lack of spare parts.

Due to its location in the restricted area of a radius of 30 nautical miles (reduced to 10 in 1967) from the center of Hanoi and its proximity to the Bach Mai Hospital 1 km away, Bach Mai Airfield was off limits to US bombers during the early years of Operation Rolling Thunder with the result that North Vietnamese command and control was generally unmolested.
