Woodsia is a genus of ferns in the family Woodsiaceae. Species of Woodsia are commonly known as cliff ferns.^[4]^: 224 In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it was the only genus in the family Woodsiaceae.^[1] In 2020, Physematium was split off from Woodsia on the basis of molecular phylogenetic evidence.^[5] As of June 2023^[update], Plants of the World Online continued to treat Physematium as a synonym of Woodsia.^[6]

Woodsia × tryonis B.Boivin = W. ilvensis × W. glabella

When the genus Physematium is accepted, × Woodsimatium abbeae is a hybrid between Woodsia ilvensis and Physematium scopulinum.^[10]
