Phyllomedusa iheringii is a species of frog in the subfamily Phyllomedusinae.

It is found in southernmost Brazil (Rio Grande do Sul) and Uruguay.

[1][2] The specific name iheringii honors Hermann von Ihering, a German-Brazilian zoologist.

[1][2] Phyllomedusa iheringii occurs in shrubland at elevations less than 500 m (1,600 ft).

The eggs are laid on vegetation above standing water where the tadpoles develop.
