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.{{cite web |url=http://research.amnh.org/vz/herpetology/amphibia/Amphibia/Anura/Dicroglossidae/Dicroglossinae/Nannophrys |title=Nannophrys Günther, 1869 |author=Frost, Darrel R. |year=2015 |work=Amphibian Species of the World: an Online Reference.
