The dingo (Canis lupus dingo) is a free-roaming dog found mainly in Australia, as well as Southeast Asia, where it is said to have originated. It is currently classified as a subspecies of the grey wolf, Canis lupus.

A dingo's habitat ranges from deserts to grasslands and the edges of forests. Dingoes will normally make their dens in deserted rabbit holes and hollow logs close to an essential supply of water.

The dingo is the largest terrestrial predator in Australia, and plays an important role as an apex predator. However, the dingo is seen as a pest by sheep farmers due to frequent attacks on livestock. Conversely, their predation on rabbits, kangaroos and rats is of benefit to cattle stations.

For many Australians, the dingo is a cultural icon. As a result, there is fear of the species becoming extinct, similar to the case of the thylacine in Tasmania, commonly known as the Tasmanian tiger, thought to have become extinct in the 20th century. The dingo is seen by many as being responsible for thylacine extinction on the Australian mainland about two thousand years ago, although a recent study challenges this view. Dingoes have a prominent role in the culture of Aboriginal Australians as a feature of stories and ceremonies, and they are depicted on rock carvings and cave paintings.
