'''''Asplenium''''' is a [[genus]] of about 700 [[species]] of [[fern]]s, often treated as the only genus in the [[family (biology)|family]] [[Aspleniaceae]], though other authors consider ''[[Hymenasplenium]]'' separate, based on [[molecular phylogenetic]] analysis of [[DNA sequence]]s, a different chromosome count, and structural differences in the rhizomes. The [[type species]] for the genus is ''[[Asplenium marinum]]''.

The most common vernacular name is '''spleenworts''', applied to the more "typical" species. ''[[Asplenium nidus|A. nidus]]'' and several similar species are called '''[[bird's-nest fern]]s''', the ''Camptosorus'' group is known as '''[[walking fern]]s''', and distinct names are applied to some other particularly well-known species.
