Thelypteris (maiden ferns[3]) is a genus of ferns in the subfamily Thelypteridoideae, family Thelypteridaceae, order Polypodiales.[1][4] Two radically different circumscriptions of the genus are in use as of January 2020. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the genus is a very small one with about two species.[1][2] In other approaches, the genus is the only one in the subfamily Thelypteridoideae, and so includes between 875[5] and 1083 species.[6]

The genus name is from Greek thēlys "female" and pteris "fern". However, "female fern" usually refers to the common lady-fern.
