Scinax is a genus of frogs, commonly known as snouted treefrogs, in the family Hylidae. The genus is found from eastern and southern Mexico to Argentina and Uruguay, and in Trinidad and Tobago, and Saint Lucia. Member species are small to moderate-sized tree frogs, drably colored. Duellman and Wiens resurrected this genus in 1992. The name originates from the Greek word skinos, meaning quick or nimble.

Hylidae is a wide-ranging family of frogs commonly referred to as "tree frogs and their allies". However, the hylids include a diversity of frog species, many of which do not live in trees, but are terrestrial or semiaquatic.
