Airport West is a suburb in Melbourne, Victoria, Australia, 12 km (7.5 mi) north-west of Melbourne's Central Business District, located within the City of Moonee Valley local government area. Airport West recorded a population of 8,173 at the 2021 census.

Bounded by the Calder Freeway to the south, the Tullamarine Freeway to the east, and the Western Ring Road to the north west, Airport West is so named for its position to the west of Essendon Airport, Melbourne's first general airport now used for light planes, charter and freight since the opening in 1970 of Melbourne Airport, located to the north of the suburb.

It has the distinction of being the only locality in Australia which does not itself contain an airport to contain the word "Airport."

This area shares a postcode and, for a time, a name with neighboring Niddrie. In the late 1950s a group of aviation related businesses along Matthews Ave petitioned for a name which might better reflect their location and help their businesses.

The present Airport West post office opened on 22 November 1982. The Niddrie North office which opened in 1960 was known as Airport West between 1974 and 1982, before reverting back to Niddrie North.
