The McDonnell Douglas A-4G Skyhawk is a variant of the Douglas A-4 Skyhawk attack aircraft developed for the Royal Australian Navy (RAN). The model was based on the A-4F variant of the Skyhawk, and was fitted with slightly different avionics as well as the capacity to operate AIM-9 Sidewinder air-to-air missiles. The RAN received ten A-4Gs in 1967 and another ten in 1971, and operated the type from 1967 to 1984.

In Australian service the A-4Gs formed part of the air group of the aircraft carrier HMAS Melbourne, and were primarily used to provide air defence for the fleet. They took part in exercises throughout the Pacific region and also supported the training of RAN warships as well as other elements of the Australian military. The Skyhawks did not see combat, and a planned deployment of some of their pilots to fight in the Vietnam War was cancelled before it took place. Ten A-4Gs were destroyed as a result of equipment failures and non-combat crashes during the type's service with the Navy, causing the deaths of two pilots.

The RAN had no need for most of its fixed-wing aircraft after Melbourne was decommissioned in 1982, and the ten remaining A-4Gs were sold to the Royal New Zealand Air Force (RNZAF) in 1984 where they were initially used for training purposes. Between 1986 and 1991 these aircraft were upgraded and re-designated A-4Ks. Two of the former A-4Gs crashed during 2001, resulting in the death of a pilot. The RNZAF's Skyhawks were retired in 2001. Eight A-4Ks, including six former A-4Gs, were sold to Draken International in 2012 and are in service supporting United States military training exercises.

During the late 1950s the Australian Government and Royal Australian Navy (RAN) considered options to replace the aircraft carrier HMAS Melbourne, and her air group. While Melbourne had only been commissioned in 1955, the de Havilland Sea Venom fighters and Fairey Gannet maritime patrol aircraft operated by the Fleet Air Arm (FAA) were becoming obsolete. It was believed that Melbourne was too small to operate more modern aircraft types, and the RAN investigated options to buy a larger carrier. The Government judged that the cost of a new aircraft carrier was too high, especially given the expense of the Australian Army and Royal Australian Air Force's (RAAF's) procurement programs at that time, and in November 1959 it was announced that the FAA would cease to operate fixed-wing aircraft in 1963.
