Crossodactylus boulengeri is a species of frog in the family Hylodidae.

It lives in the Serra do Mar mountain range in São Paulo and Rio de Janeiro in Brazil.

[1][2] For some time, scientists considered this frog a junior synonym of Crossodactylus dispar.

In 2014, a new study confirmed that they are truly two different species.
