Caversham Airfield, also known as Middle Swan Airfield was an airfield constructed at Caversham, Western Australia during World War II as a parent aerodrome for use by the Royal Navy's Fleet Air Arm and the United States Navy.

The airfield had a triangle of three landing strips.

Middle Swan was the parent airfield with the following satellite airfields:

• Beverley
• Bindoon
• Gingin North
• Mooliabeenee

The United States Army Air Corps also utilised the airfield during World War II.

It was also a gliding club location after the war.

In 1956 the Western Australia Sporting Car Club gained a lease for the property, which was then converted into a permanent circuit. It became Western Australia's premier motor racing venue, hosting the Australian Grand Prix in 1957 and 1962 and the Six Hour Le Mans endurance race from 1955 to 1968. Racing activities ceased when the airfield was re-activated as a military facility for radio communications, and Western Australian racing shifted to Wanneroo Raceway in 1969.
