Phrynopus montium is a species of frog in the family Strabomantidae.

[1][2] The type series consists of four unsexed individuals measuring 21–29 mm (0.83–1.14 in) in length.

There are a few small pale yellow spots on each side of the dorsum, sometimes even on the flank.

Two specimens were spotted under rocks in an open area with scattered bushes, Sphagnum moss, and bunchgrass (Stipa sp.)

[3] The International Union for Conservation of Nature (IUCN) assessed Phrynopus montium in 2004 as "endangered",[1] but understanding of its distribution has since markedly changed.
