The Australian Manufacturers' Championship was a motor racing title awarded by the Confederation of Australian Motor Sport (CAMS) to the winning car manufacturer in an annual series of races held throughout Australia. Whilst the first two championships were open only to Group E Series Production Touring Cars subsequent championships through to 1991 were run to the same regulations as the Australian Touring Car Championship. The title has been revived twice since then, firstly in 1994 as a championship open to 2-litre Class II Touring Cars and from 2008 as a series for production cars, incorporating the Australian Production Car Championship.

The Australian Production Car Championship is an Australian motor racing title for production cars, sanctioned by the Confederation of Australian Motor Sport (CAMS). The championship was first contested in 1987 and from 2008 to 2015 the title was awarded to the most successful driver in the annual Australian Manufacturers' Championship series which ran on the Shannons Nationals Motor Racing Championships program.
