A domestic goose is a goose that humans have domesticated and kept for their meat, eggs, or down feathers. Domestic geese have been derived through selective breeding from the wild greylag goose and swan goose.

A goose is a bird of any of several waterfowl species in the family Anatidae. This group comprises the genera Anser and Branta. Some members of the Tadorninae subfamily are commonly called geese, but are not considered "True Geese" taxonomically. More distantly related members of the family Anatidae are swans, most of which are larger than true geese, and ducks, which are smaller.
