Hyloidea is a superfamily of frogs. Hyloidea accounts for 54% of all living anuran species. The Hyloidea superfamily branched off from a common ancestor from the Neobatrachia suborder during the time of the Cretaceous-Paleogene extinction 66 million years ago. The fossil evidence found during this period of extinction could not determine the effects upon the frogs, due to the lack of fossils. Increased forestation erupted after this extinction, possibly leading to more arboreal adaptations of these anurans to be best suited for this habitat. It contains the following subgroups:
* Alsodidae (Mivart, 1869) - (26 species)
* Batrachylidae (Gallardo, 1965) - (14 species)
* Brachycephaloides

* Eleutherodactylidae (Lutz, 1954)- rain frogs (223 species)
* Centrolenids
* Allophrynidae (Savage, 1973) - Tukeit Hill frogs (3 species)
* Centrolenidae (Taylor, 1951) - glass frogs (155 species)
