The southern leaf green tree frog (Ranoidea nudidigitus) is a species of tree frog native to coastal areas and the ranges of south-eastern Australia.

Ranoidea nudidigitus is a small species of tree frog, up to about 40 mm (1.6 in) in length.

They are very similar to the leaf green tree frog (Ranoidea phyllochroa), and distribution and call are used to distinguish the two.

Hybridisation is possible around southern Sydney, from the Royal National Park to about Wollongong.

This species is associated with streams and creeks in rainforests, as well as wet or dry sclerophyll forests.
