The Australian Derby is a harness racing event held for three-year-old pacers which has been shared between many of Australia's premier tracks. It is currently held annually at Launceston in Tasmania. The 2007 version was won by Lombo Pocket Watch.

The Australian Derby differs from other Derbies as it is not organised by a state controlling body but the national body.

It is in a similar vein to the Australian Pacing Championship in that it is not a state specific event.
