The 1998 Australian GT Production Car Championship was a CAMS sanctioned motor racing title^[1] for drivers of Group 3E Series Production Cars. The championship, which was promoted by Procar Australia, was the third Australian GT Production Car Championship.^[2]

The title was contested over an eight round series^[3] with two races per round.^[4]

The final round had been scheduled to be run at Amaroo Park on 30 August but was moved to Oran Park on the same date.

Championship points were awarded on a 15-12-10-8-6-5-4-3-2-1 basis to the first ten classified finishers in each race. A bonus point was awarded to the driver setting pole position at each round.

Points for the five class titles were awarded on a similar basis but with no bonus point for pole position.
