The 1993 Australian 2.0 Litre Touring Car Championship was a CAMS sanctioned Australian motor racing title for drivers of under 2.0 litre cars complying with the provisions of the FISA Class II section of Australian Group 3A Touring Car regulations. It was contested in conjunction with the 1993 Australian Touring Car Championship, which began on 28 February 1993 at Amaroo Park and ended on 8 August at Oran Park Raceway after nine rounds. It was the third Australian 2.0 Litre Touring Car Championship and the first for cars aligned with FISA Class II regulations and thus the fore-runner of the Australian Super Touring Championship.
