Paratelmatobius gaigeae (common name: Gaige's rapids frog) is a species of frog in the family Leptodactylidae. It is endemic to Serra da Bocaina, a part of Serra do Mar, southeastern Brazil. Paratelmatobius gaigeae is named after Helen Beulah Thompson Gaige, an American herpetologist. Its natural habitats are montane forests. It is a terrestrial frog that probably breeds in temporary ponds or streams. It is threatened by habitat loss; logging might have already caused extirpation of this species from its type locality, Bonito in the Serra da Bocaina.
