The Australian Magpie is a medium-sized black and white passerine bird native to Australia and southern New Guinea.

The adult Australian Magpie is a fairly robust bird ranging from 37 to 43 cm (14.5–17 in) in length, with distinctive black and white plumage, gold brown eyes and a solid wedge-shaped bluish-white and black bill. The male and female are similar in appearance, and can be distinguished by differences in back markings. With its long legs, the Australian Magpie walks rather than waddles or hops and spends much time on the ground. This adaptation has led to many authorities maintaining it in its own genus Gymnorhina. Described as one of Australia's most accomplished songbirds, the Australian Magpie has an array of complex vocalisations. The Australian Magpie is omnivorous, with the bulk of its varied diet made up of invertebrates. It is generally sedentary and territorial throughout its range. Common and widespread, it has adapted well to human habitation and is a familiar bird of parks, gardens and farmland in Australia and New Guinea. Magpies were introduced into New Zealand in the 1860s and are proving to be a pest by displacing native birds. Introductions also occurred in the Solomon Islands and Fiji, where the birds are not considered an invasive species.

Spring in Australia is magpie season, when a small minority of breeding magpies (almost always males) around the country become aggressive and swoop and attack those who approach their nests, especially bike riders.

This species is commonly fed by households around the country and is the mascot of several Australian sporting teams.
