'''Pseudis''' is a genus of frogs in the Hylidae family, and are found in Guianas, Venezuela, Trinidad, southern Brazil, Paraguay, southeastern Peru, eastern Bolivia, northeastern Argentina and Uruguay.
''Pseudis'' is a genus of aquatic frogs distributed throughout South America, East of the Andes. They are commonly found in ponds associated to river floodplains, from Trinidad to northern Argentina, being absent only in Ecuador and Chile. Most species occur in Brazil, and ''P. fusca'', ''P. tocantins'', ''P. cardosoi'', and ''P. bolbodactyla'' are endemic to this country.

These frogs have several adaptations to aquatic life, such as protuberant eyes, robust hindlimbs, and fully webbed feet. Nevertheless, they are more closely related to tree frogs.

These frogs are commonly known because of their giant tadpole that can reach up to 26 cm (about 10 inches). They are closely related to a second genus, ''Lysapsus'', that lacks giant tadpoles and which adults are about 2 cm long (less than an inch).
