The Inspector-General of the RAF was a senior appointment in the Royal Air Force, responsible for the inspection of airfields. The post existed from 1918 to 1920 and from 1935 until the late 1960s. For much of World War II, a second inspector-general post existed.
The first creation of the post began on 22 August 1918 as a member of the Air Council. However, in February or March of the following year, the Inspector-General ceased to sit on the Air Council.
