1984 Australian Touring Car season

The 1984 Australian Touring Car season was the 25th season of touring car racing in Australia, commencing in 1960 when the first Australian Touring Car Championship and the first Armstrong 500 (the forerunner of the present day Bathurst 1000) were contested. It was the last season in for the locally developed Group C category before the adoption of FIA's Group A rules from 1985.

Touring Cars competed at 17 race meetings in Australia during the 1984 season, contesting the following events:

• The seven rounds of the 1984 Australian Touring Car Championship (ATCC)
• The five rounds of the 1984 Australian Endurance Championship
• The four rounds of the 1984 AMSCAR series, held exclusively at Amaroo Park (each round consisted of 3 races).
• A touring car support round at the 1984 Australian Grand Prix meeting held at Calder Park. This was the last Australian Grand Prix held before the race became a part of the Formula One World Championship from 1985.
