Robin John "Bob" Holden is an Australian racing driver. Holden raced small-engined touring cars throughout his career, racing Peugeots in the early 1960s, establishing a reputation for himself which saw him become a regular part of BMC Australia racing program for Minis which culminated with a victory in the 1966 Bathurst 500 co-driving with Rauno Aaltonen. Into the 1970s Holden moved on to race Ford Escorts in various guises, moving into Toyota Corollas in the 1980s, winning the 1.6-litre class at the Bathurst round of the 1987 World Touring Car Championship. In the mid-1990s Holden moved into BMW M3s and later a BMW 318i Super Touring car in which he raced his final Bathurst in 1998, at the time setting the record for most Bathurst appearances.

The 1966 Gallaher 500 was an endurance motor race for production cars, held on 2 October 1966 at the Mount Panorama Circuit just outside Bathurst, New South Wales in Australia. It was the seventh running of the Bathurst 500 race and the first time that the event had been staged under the Gallaher 500 name. 250 examples of a particular model had to be registered for a vehicle to be eligible for the race, up from the 100 examples required in previous years.
