Megaelosia is a genus of frogs in the Hylodidae family. The genus is endemic to the Serra do Mar and Serra da Mantiqueira in southeastern Brazil. These frogs are sometimes known as the big-tooth frogs.

This might be associated with their predatory habits: at least two species are known prey on small vertebrates as well as invertebrates. The tadpoles are aquatic. Megaelosia are relatively large frogs, with adults attaining lengths up to 120 mm (4.7 in) in snout–vent length.
