Yowie is the term for an unidentified hominid reputed to lurk in the Australian wilderness. It is an Australian cryptid similar to the Himalayan Yeti and the North American Bigfoot.

The origins of the yowie (also "Yowie-Whowie" and yahoo) may lie in a mythological character in native Australian Aboriginal folklore. This creature's characteristics and legend are sometimes interchangeable with those of the bunyip. According to some writers, reports of yowie-type creatures are common in the legends and stories of Australian Aboriginal tribes, particularly those of the eastern states of Australia.

The origin of the term "yowie" in the context of unidentified hominids is unclear. Some nineteenth century writers suggested that it simply arose through the aforementioned Aboriginal legends. Robert Holden recounts several stories that support this from the nineteenth century, including this European account from 1842;

Another story, collected from an Aboriginal source, seems to confirm the creature as a part of the Dreamtime.
