The 2015 Liqui Moly Bathurst 12 Hour was an endurance race for a variety of GT and touring car classes, including: GT3 cars, GT4 cars and Group 3E Series Production Cars. The event, which was staged at the Mount Panorama Circuit, near Bathurst, in New South Wales, Australia on 8 February 2015, was the thirteenth running of the Bathurst 12 Hour.

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.
