Grammitis is a genus of ferns in the family Polypodiaceae. It had formerly been placed in the family Grammitidaceae but this family is no longer recognized by most authors because phylogenetic analyses of DNA sequences have shown that it is embedded in Polypodiaceae. The delimitation of Grammitis was drastically narrowed in the first decade of the 21st century. It now contains about 25 species.
