Cane Toads: An Unnatural History is a 1988 documentary film about the introduction of cane toads to Australia. Cane toads were introduced to Australia with the aim of controlling a sugar cane pest, the cane beetle, but they over-multiplied and became a serious problem in the Australian ecosystem. It is often humorous, and is used in high schools and colleges as a complement to curricula in biology, ecology, environmental science, anthropology, geography, and communication. It was filmed in Cairns and Gordonvale in Queensland.

The film was nominated for a BAFTA Film Award for Best Short Film. It is distributed in the United States by Radio Pictures.

Unusual for a film considered a cult classic, Cane Toads performed very well during its theatrical release. Released in March 1988, the film grossed $613,910 Australian dollars (not adjusted for inflation) as of 2012 and has been one of the top grossing Australian documentaries of all time.
