Onychognathus is a genus of starlings native to the Afrotropical realm.

All the species are quite similar, and characterised by rufous primary wing feathers, very obvious in flight. The males are typically mainly glossy black, and the females have dull (sometimes dark, depending on species) grey heads.

The genus was introduced by the German physician and ornithologist Gustav Hartlaub in 1849 with the chestnut-winged starling as the type species.{{ cite journal | last=Hartlaub | first=Gustav | author-link=Gustav Hartlaub | year=1849 | title=Description de cinq nouvelles espèces d'oiseaux de l'Afrique occidentale | language=French, Latin | journal=Revue et Magasin de Zoologie Pure et Appliquée | series=2nd Series | volume=1 | pages=494–499 [494] | url=https://biodiversitylibrary.org/page/2343874 }} The name Onychognathus combines the Ancient Greek words onukhos "claw" or "nail" and gnathos "jaw".{{cite web | last=Jobling | first=J.A. | year=2018 | title= Key to Scientific Names in Ornithology | editor1-last=del Hoyo | editor1-first=J. | editor2-last=Elliott | editor2-first=A. | editor3-last=Sargatal | editor3-first=J. | editor4-last=Christie | editor4-first=D.A. | editor5-last=de Juana | editor5-first=E. | work=Handbook of the Birds of the World Alive | publisher=Lynx Edicions | url=https://www.hbw.com/dictionary/definition/onychognathus | accessdate=11 May 2018 }}
