Gastrotheca griswoldi is a species of frog in the family Hemiphractidae. The species is endemic to central Peru.
The specific name, griswoldi, honours John Augustus Griswold Jr (1912–1991), an American aviculturist and ornithologist.
The "common name", Griswold's marsupial frog, has been coined for G. griswoldi.
G. griswoldi is known from the Huánuco, Junín, and Pasco Regions of Peru.
The natural habitats of G. griswoldi are dry puna grasslands, including traditionally cultivated arable land, at elevations of 3,000–4,020 m (9,840–13,190 ft) asl.
