Phrynobatrachus werneri is a species of frog in the family Phrynobatrachidae.

[2][3] It is only known with certainty from western Cameroon, although there is a putative record from Chappal Waddi in Nigeria, close to the border of Cameroon; the earlier record from the Obudu Plateau in Nigeria is now assigned to Phrynobatrachus schioetzi described as a new species in 2011.

[2][3][5] The specific name werneri honours Franz Werner, an Austrian explorer, zoologist, and herpetologist.

Males have a black throat and some darker pigmentation on the chest and anterior of the belly.

[3] Phrynobatrachus werneri is found in and around small bodies of water such as streams, roadside ditches, Raphia swamps and marshes in submontane and montane forest and grassland landscapes.
