Gastrophryne, the narrowmouth toads (also American narrowmouth toads, North American narrow-mouthed toads), is a genus of microhylid frogs found in the Americas between Honduras and southern United States. Its name means ‘belly-toad’, referring to its large belly, from the Ancient Greek gastēr (γαστήρ, ‘belly, stomach’) and phrunē (φρύνη, ‘toad’).
Gastrophryne is closely related to Hypopachus. Some species that were earlier placed in Gastrophryne were more closely related to Hypopachus, rendering the genus paraphyletic. This has been rectified by moving some species (Gastrophryne usta and Gastrophryne pictiventris) to Hypopachus.
The currently recognized species are:
- Gastrophryne carolinensis (Holbrook, 1835) - eastern narrow-mouthed toad
- Gastrophryne elegans (Boulenger, 1882) - elegant narrow-mouthed toad
- Gastrophryne mazatlanensis (Taylor, 1943)
- Gastrophryne olivacea (Hallowell, 1856) - Great Plains narrow-mouthed toad
