Nannophrys is a genus of frogs endemic to Sri Lanka.

It used to be placed in the large frog family Ranidae but a phylogenetic study was undertaken using DNA sequences and it is now included in the family Dicroglossidae.

They are sometimes known under the common name streamlined frogs.

[1][2] Nannophrys species are flat-bodied frogs that are adapted to live among narrow, horizontal rock crevices near clear-water streams.
