'''''Gymnocarpium dryopteris''''' ('''Western Oakfern''', '''Common Oak Fern''' or '''Northern Oak Fern''') is a fern of the family [[Polypodiaceae]]. It has small, delicate fronds with ternately-compound pinnae (leaves). Fronds occur singly. On the underside of matured pinnae naked sori can be found. Common in the [[Canada|Canadian]] forests, it is also found in [[Scotland]] and [[Scandinavia]] as well as North Western United States.<ref name="Burke">{{cite web|title=Gymnocarpium dryopteris|work=WTU Herbarium Image Collection |publisher=Burke Museum, University of Washington|url=http://biology.burke.washington.edu/herbarium/imagecollection.php?Genus=Gymnocarpium&Species=dryopteris|accessdate= 2009-12-20}}</ref><ref name="PLANTS">{{cite web | title = Gymnocarpium dryopteris (L.)

''Oakfern'' may be a translation of ''dryoteris''. This species, a forest understory plant, is not found in association with ''[[Quercus]]'' (oak).<ref>Plants of the Pacific Northwest Coast: Washington, Oregon, British Columbia & Alaska, Written by Paul Alaback, ISBN 978-1-55105-530-5</ref><ref name="Pojar">{{cite book | last = Pojar | first = Jim | coauthors = Andy MacKinnon | title = Plants of the Pacific Northwest | publisher = Lone Pine Publishing | page = 423 | date = 1994 | id = ISBN 1-55105-042-0}}</ref>
