The Inter Dominion Trotting Championship Grand Final was a race for trotters within the overall Inter Dominion series. The series is held each year, and is a harness racing competition for both trotters and pacers that has been contested since 1936 in Australia and New Zealand. The host of the series is rotated between the 6 harness racing states of Australia and the North and South Islands of New Zealand. However, in recent years the Trotting series has mainly been held in Victoria with other Australian states reluctant to host the series. It forms part of the overall Inter Dominion series for pacers and trotters.
