Derby Airport is located southeast of Derby, Western Australia.
The site of Derby airport was first set aside for aviation uses in 1922. The airfield played a key role in the search for Charles Kingsford Smith's Southern Cross following a forced landing in the Kimberley region during 1929 in an incident that would become known as the "Coffee Royal Affair". Aviation pioneer Norman Brearley used aircraft of his West Australian Airways in the initial search effort flying outwards from Derby.
In 1938, it was proposed that Derby to be used as a base for flying boat services carried air mail from London to Australia via Egypt and Ceylon (Sri Lanka).
