Nyctibatrachus is a genus of frogs endemic to the Western Ghats of southwestern India. Their common name is night frogs.{{cite web |url=http://research.amnh.org/vz/herpetology/amphibia/Amphibia/Anura/Nyctibatrachidae/Nyctibatrachus |title=Nyctibatrachus Boulenger, 1882 |author=Frost, Darrel R. |year=2015 |work=Amphibian Species of the World: an Online Reference.

Description
Members of the genus Nyctibatrachus are robust-bodied frogs that range in size from small (snout–vent length <13 mm in Nyctibatrachus robinmoorei){{cite journal|last1=Garg|first1=Sonali|last2=Suyesh|first2=Robin|last3=Sukesan|first3=Sandeep|last4=Biju|first4=SD|title=Seven new species of Night Frogs (Anura, Nyctibatrachidae) from the Western Ghats Biodiversity Hotspot of India, with remarkably high diversity of diminutive forms|journal=PeerJ|date=21 February 2017|volume=5|pages=e3007|doi=10.7717/peerj.3007|pmid=28243532|language=en|issn=2167-8359|pmc=5322763 |doi-access=free }} to relatively large (up to 84 mm Nyctibatrachus karnatakaensis). The especially small species are among the smallest of all Indian frogs. They have a concealed tympanum, dorsum with longitudinal skin folds, femoral glands, and expanded finger and toes disks. They occur near streams in hilly evergreen forests{{cite book|title=Herpetology: An Introductory Biology of Amphibians and Reptiles |edition=4th |first1=Laurie J.|last1= Vitt|first2=Janalee P. |last2=Caldwell|publisher=Academic Press|year=2014|pages=509–510}} and are nocturnal.{{cite journal | author = Biju, S.D., Van Bocxlaer, I., Mahony, S., Dinesh, K.P., Radhakrishnan, C., Zachariah, A., Giri, V., and Bossuyt, F. | year = 2011 | title =A taxonomic review of the Night Frog genus Nyctibatrachus Boulenger, 1882 in the Western Ghats, India (Anura: Nyctibatrachidae) with description of twelve new species | journal = Zootaxa| volume =3029 | pages = 1–96| doi = 10.11646/zootaxa.3029.1.1|url= http://www.mapress.com/zootaxa/2011/f/z03029p096f.pdf}} Most species have amplexus but Nyctibatrachus humayuni does not; in this species the male moves over the eggs after the female has deposited them.
