The domestic goat (Capra aegagrus hircus) is a subspecies of goat domesticated from the wild goat of southwest Asia and Eastern Europe. The goat is a member of the Bovidae family and is closely related to the sheep, both being in the goat antelope subfamily Caprinae.

Domestic goats are one of the oldest domesticated species. For thousands of years, goats have been used for their milk, meat, hair, and skins over much of the world. In the last century they have also gained some popularity as pets.

Female goats are referred to as does or nannies (or, less frequently, as mishas), intact males as bucks or billies; their offspring are kids. Castrated males are wethers. Goat meat from younger animals is called kid, and from older animals is sometimes called chevon, or in some areas mutton.
