The 1987 Australian Manufacturers' Championship was a CAMS sanctioned motor racing title for car manufacturers. The title, which was the seventeenth Australian Manufacturers' Championship, was contested concurrently with the 1987 Australian Touring Car Championship over a nine round series.
Each round was open to cars complying with CAMS Touring Car regulations which were based on international Group A Touring Car rules. Cars competed in two engine capacity classes:
Championship points were awarded on a 20-15-12-10-8-6-4-3-2-1 basis for the top ten placings in each class at each round. However, points were only allocated for the best placed car from each manufacturer at each round and only the best eight round results could be retained by each manufacturer.
