Woodwardia (chain fern) is a genus of 14 to 20 species of ferns in the family Blechnaceae, in the eupolypods II clade[2] of the order Polypodiales,[3] in the class Polypodiopsida.[4] It is native to warm temperate and subtropical regions of the Northern Hemisphere. They are large ferns, with fronds growing to 50–300 cm long depending on the species.

The genus was named after Thomas Jenkinson Woodward.[5]
