The guineafowl ( /ˈɡɪnifaʊl/; sometimes called guineahen) are a family of birds in the Galliformes order, although some authorities (for example the American Ornithologists' Union) include the guineafowl as a subfamily, Numidinae, of the family Phasianidae. The guineafowl are native to Africa, but the Helmeted Guineafowl has been domesticated, and both feral and wild-type birds have been introduced elsewhere.
