Ridgway's hawk (Buteo ridgwayi) (Spanish: gavilán de la Española, gavilán dominicano, guaraguaito) is a bird of prey in the family Accipitridae endemic to the island of Hispaniola (both Haiti and the Dominican Republic) in the Caribbean. It is classified as Critically Endangered because of habitat destruction and human persecution in the Dominican Republic; however, due to conservation efforts, the population is now increasing. It is named in honour of the ornithologist Robert Ridgway.
