Athyrium (lady-fern) is a genus of about 180 species of terrestrial ferns, with a cosmopolitan distribution. It is placed in the family Athyriaceae, in the order Polypodiales.[1][2] Its genus name is from Greek a- ('without') and Latinized Greek thureos ('shield'), describing its inconspicuous indusium (sorus' covering).[3] The common name "lady fern" refers in particular to the common lady fern.[4]

Athyrium species are used as food plants by the larvae of some Lepidoptera species including Small Angle Shades and Sthenopis auratus.
