The 2012 Armor All Bathurst 12 Hour was an endurance race for GT3 cars, GT4 cars, Group 3E Series Production Cars and Dubai 24 Hour cars. The event, which was staged at the Mount Panorama Circuit, near Bathurst, in New South Wales, Australia on 26 February 2012, was the tenth running of the Bathurst 12 Hour, and the sixth since the race was revived in 2007.

The Bathurst 12 Hour, currently known as the Repco Bathurst 12 Hour for sponsorship reasons, is an annual endurance race for GT and production cars held at the Mount Panorama Circuit, in Bathurst, Australia. The race was first held in 1991 for Series Production cars and moved to Sydney's Eastern Creek Raceway in 1995 before being discontinued. The race was revived in 2007, again for production cars, before adding a new class for GT3 and other GT cars in 2011. This has led to unprecedented domestic and international exposure for the event. In all, twenty one races have taken place; twenty at Mount Panorama and one at Eastern Creek Raceway.
