The 1965 Armstrong 500 was the sixth running of the Bathurst 500 touring car race. It was held on 3 October 1965 at the Mount Panorama Circuit just outside Bathurst, New South Wales, Australia. The race was open to Australian assembled or manufactured vehicles and, for the first time, to imported vehicles, of which at least 100 examples and 250 examples respectively had been registered in Australia. Cars competed in four classes based on the purchase price of the vehicle in Australian pounds. Prize money was on offer only for class placings however the Armstrong Trophy was presented to the entrant of the outright winning car, this being the first time in the history of the event that there had been an official award for the outright winner.
