The RAF Third Tactical Air Force (Third TAF), which was formed in South Asia in December 1943, was one of three tactical air forces formed by the Royal Air Force (RAF) during the Second World War. It was made up of squadrons and personnel from the RAF, Indian Air Force (IAF) and the air forces of other Commonwealth countries. Third TAF was formed shortly after the establishment of South East Asia Command to provide close air support to the Fourteenth Army.

It was first formed on 19 December 1943 designated the Tactical Air Force (Burma) and renamed as the Third TAF on 28 December 1943. Along with parts of the USAAF Tenth Air Force, it was subordinate to Joint Allied Eastern Air Command which was also formed in December 1943.

As the Air Force was formed, it was felt that at last British forces could go over to the offensive against the Japanese in the Burma Campaign. A start was made towards establishing a general offensive in Arakan in early 1943, but this was forestalled by a Japanese offensive. The Japanese were decisively beaten, but they shifted the focus of their attack to central Burma. Third TAF gave sterling service to Fourteenth Army during the Battle of Kohima and the Battle of Imphal, strafing and bombing the besieging Japanese troops, often at very low level.

After the defeat of the Japanese by IV Corps and XXXIII Corps in Assam, the monsoon intervened before many counterattacks could take place. After the enforced period of reduced operations, the Third TAF supported the advance of Fourteenth Army against the Japanese forces. However, command arrangement changes at the end of 1944 cutting short the life of the Third TAF. It was redesignated HQ RAF Bengal and Burma on 4 December 1944.

The Third TAF had two commanders, Air Marshal John Baldwin up until 15 August 1944, and then Air Marshal Sir Alec Coryton.
