Nannophrys naeyakai is a species of frog in the Dicroglossidae family. It is endemic to Sri Lanka, where it is only known from two localities in Ampara and Monaragala Districts between 200 and 620 m above sea level. It was described as a new species in 2007. N. naeyakai can be distinguished from the other Nannophrys species by the details of the tubercles on the fourth toe, sharp and narrow symphysial knob on the anterior edge of mandible and small palmar tubercles.
