Avalon Airport (IATA: AVV, ICAO: YMAV) is an international airport, located in Avalon in the City of Greater Geelong in Victoria, Australia. While located outside the Melbourne metropolitan area, it is the second busiest of the four airports serving the state capital in passenger traffic. It is located 15 km (9 mi) north-east of the Geelong CBD and 50 km (31 mi) south-west of the Melbourne CBD. The airport is operated by Avalon Airport Australia Pty Ltd, a subsidiary of Linfox.

Avalon is currently served by passenger airline Jetstar, which began domestic flights in 2004. The airport is also the site of the biennial Australian International Airshow, which has been held at the venue since 1992.

Unlike Melbourne Airport, Avalon Airport is not governed by the Commonwealth's Airports Act 1996. The airport has a single runway in addition to a helipad.

The airport is located on land of the original indigenous owners, the Wathaurong people, and a scatter stone area is preserved on the Avalon Airport site, out of respect for the original owners. The land has undergone many changes over the past century.

In the beginning, the airport was a sheep and cattle farm and homestead, founded by James Austin, an immigrant from Glastonbury, England. Austin established his farm and named the homestead "Avalon" after the isle of Avalon at Glastonbury, the mythical island in the Arthurian legend. In 1952 the Commonwealth Government bought 1,754 ha (4,333 acres) at Avalon for just £110, as the land was deemed to be of poor quality farmland due to the abundance of volcanic rock littering the surface.

The airport was opened in 1953, to cater for the production of military aircraft. Previously, the Government Aircraft Factories at Fishermans Bend, Melbourne had used a runway beside the factory. However, newer jet aircraft required a longer runway for safe operations, and the Fishermans Bend runway was being encroached upon by development.

A 3,048 m (10,000 ft) runway was built by the Country Roads Board, with the first plane landing on 3 April 1953 – a four-engined Avro Lincoln heavy bomber flown from Fishermans Bend. The English Electric Canberra light bomber was under construction at the same time at the new airport. In 1959, Qantas established a training base at the site.

In 1961, Government Aircraft Factories combined with the Commonwealth Aircraft Corporation, and built and serviced 110 Mirage fighters at the site, and in 1970 Jindivik Target Aircraft transferred to Avalon Airport from Fishermans Bend, adding production of 170 Nomad and 75 Hornet military jets, in addition to servicing of other jets.^{[citation needed]}
