The 1971 Australian Formula 2 Championship was a CAMS sanctioned motor racing title for drivers of Australian Formula 2 racing cars. It was the fifth Australian Formula 2 Championship.
The championship was contested over a six heat series with one race per heat. Heats were staged concurrently with those of the 1971 Australian Drivers' Championship which was open to drivers of both Australian Formula 1 and Australian Formula 2 cars.
Championship points were awarded on a 9-6-4-3-2-1 basis to the first six placegetters in the Formula 2 class at each heat. Each driver could retain points only from his/her best five heat results.
