Gastrophryne elegans, the elegant narrow-mouthed toad, is a species of frog in the family Microhylidae found in Central America.

On either side is a reddish-brown area and then a dark-brown line that runs from the tip of the snout, past the eye, over the shoulder to the groin.

The thighs have two dark bands and further lines occur on the lower leg which align when the animal is crouched.

[2] Gastrophyrne elegans is native to lowland Mexico, Guatemala, Belize, and Honduras on the Atlantic side of the continent.

[1] The IUCN rates Gastrophryne elegans as "Least Concern", because of its large population, wide distribution, and tolerance of modifications to its habitat.
