Interwar military aircraft are military aircraft that were developed and used between World War I and World War II.
For the purposes of this list this is defined as aircraft that entered service into any country's military after the armistice on 11 November 1918 and before the Invasion of Poland on 1 September 1939.
Aircraft are listed alphabetically by their country of origin. Civilian aircraft modified for military use are included but those that remained primarily civilian aircraft are not.
