The Canada Goose (Branta canadensis) is a wild goose belonging to the genus Branta, which is native to arctic and temperate regions of North America, having a black head and neck, white patches on the face, and a brownish-gray body. It is often called the Canadian Goose, but that name is not the ornithological standard, or the most common name.

The Canada Goose was one of the many species described by Linnaeus in his 18th-century work Systema Naturae. It belongs to the Branta genus of geese, which contains species with largely black plumage, distinguishing them from the grey species of the Anser genus. The specific epithet canadensis is a New Latin word meaning "from Canada". According to the Oxford English Dictionary, the first citation for the 'Canada Goose' dates back to 1772. The Cackling Goose was formerly considered to be a set of subspecies of the Canada Goose. A recent proposed revision by Harold Hanson suggests splitting Canada Goose into six species and 200 subspecies. The radical nature of this proposal has provoked surprise in some quarters, such as Rochard Banks of the AOU, who urges caution before any of Hanson's proposals are accepted.
