Air Marshal (Air Mshl or AM) is a 3 star air officer rank which originated in and continues to be used by the Royal Air Force. The rank is also used by the air forces of many countries which have historical British influence and it is sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. Officers in the rank of Air Marshal typically hold very senior appointments such commander-in-chief of an air force or a large air force formation. Officers in the ranks of Air Chief Marshal and Air Vice-Marshal are sometimes considered generically to be air marshals. Occasionally, air force officers of marshal rank are considered to be air marshals.
Prior to the adoption of RAF-specific rank titles in 1919, it was suggested that the RAF might use the Royal Navy's officer ranks, with the word "Air" inserted before the naval rank title. For example, the rank that later became Air Marshal would have been Air Vice-Admiral. The Admiralty objected to any use of their rank titles, including this modified form, and so an alternative proposal was put forward: Air Officer ranks would be based on the term "Ardian", which was derived from a combination of the Gaelic words for "chief" (ard) and "bird" (eun), with the term "Second Ardian" or "Wing Ardian" being used specifically for the rank equivalent to a Vice-Admiral and Lieutenant-General. However, Air Marshal was preferred and was adopted on 1 August 1919. The rank of Air Marshal was first used on 11 August 1919 when Sir Hugh Trenchard was promoted to the rank and it has been used ever since.
The Australian Air Corps adopted the RAF rank system on 9 November 1920 and this usage was continued by its successor, the Royal Australian Air Force. However, the rank of air marshal was not used by the Australian Armed Forces until 1940 when Richard Williams, an RAAF officer, was promoted.
The rank insignia consists of two narrow light blue bands (each on a slightly wider black band) over a light blue band on a broad black band. This is worn on the both the lower sleeves of the tunic or on the shoulders of the flying suit or the casual uniform.
The command flag for an Air Marshal is defined by the single broad red band running in the centre of the flag.
The vehicle star plate for an Air Marshal depicts three white stars (Air Marshal is equivalent to a three star rank) on an air force blue background.

The rank of Air Marshal is also used in a number of the air forces in the Commonwealth, including the Bangladesh Air Force, Indian Air Force, Pakistan Air Force, Royal Australian Air Force and Royal New Zealand Air Force. It is also used in the Egyptian Air Force, Nigerian Air Force, Ghana Air Force, Hellenic Air Force (Antipterarchos), Air Force of Zimbabwe (including its predecessor, the Rhodesian Air Force) and the Royal Thai Air Force. In the Indonesian Air Force, the equivalent rank is Marsekal Madya (literally "Vice Marshal") which is often translated as Air Marshal in English.

In Australia, there are four appointments available for Air Marshals: the Chief of Air Force (CAF) and, at times when they are occupied by an air force officer, the Vice Chief of Defence Force (VCDF), the Chief of Joint Operations (CJOPS), and the Chief - Capability Development Group (CCDG).
In New Zealand, the head of the air force holds the lower rank of air vice-marshal. However, when an air force officer holds the country's senior military appointment, Chief of the New Zealand Defence Force, he is granted the rank of air marshal. The last air force Chief of the Defence Force was Air Marshal Sir Bruce Ferguson who served in that appointment from 2001 to 2006.
The Royal Canadian Air Force (RCAF) used the rank until the 1968 unification of the Canadian Forces, when army-type rank titles were adopted and an Air Marshal became a Lieutenant-General. In official French Canadian usage, the rank title was maréchal de l'air. The Canadian Chief of the Air Staff ordinarily held the rank of Air Marshal.
The Brazilian Air Force does not use air marshal ranks as an equivalent to general ranks, rather it uses a number of ranks based on the word brigadier. However, its highest rank is Marechal-do-ar which is a 5 star rank and equivalent to a Brazilian Army marshal. Marechal-do-ar is sometimes translated as air marshal but as it is a marshal rank, it might also be translated as marshal of the air or marshal of the air force.
Marshals of the Royal Air Force are also occasionally described as air marshals.
