Nanohyla nanapollexa is a species of frog in the family Microhylidae.

It is endemic to Vietnam[1][2] and is known from Quang Nam and Phu Yen Provinces.

[2] N. nanapollexa was formerly placed in the genus Microhyla, but a 2021 study using morphological and phylogenetic evidence moved nine species (including N. nanapollexa) to a new genus, Nanohyla.

[2][3] The type locality of Nanohyla nanapollexa is a montane broad-leaved evergreen forest with small mixed coniferous areas at 1,480 m (4,860 ft) above sea level.

N. nanapollexa is considered data deficient by the IUCN Red List.
