'''''Polyphlebium''''' is a fern genus in the family Hymenophyllaceae. The genus is accepted in the Pteridophyte Phylogeny Group classification of 2016 (PPG I) but not by some other sources.

==Taxonomy== The genus ''Polyphlebium'' was erected by Edwin Copeland in 1938.<ref name=CFLW/> Its status, like other genera in the family Hymenophyllaceae, remains disputed. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) accepts the genus, saying that there are about 15 species.<ref name=PPGI/> {{As of|2019|October}}, the ''Checklist of Ferns and Lycophytes of the World'' lists 17 species,<ref name=CFLW/> whereas ''Plants of the World Online'' sinks the genus into ''Trichomanes''.<ref name=POWO_17411610-1/>
