Dryopteris goldiana, commonly called Goldie's wood fern, or giant wood fern is a fern native to the eastern United States and adjacent areas of Canada, from New Brunswick to Ontario and Georgia. It is the largest native North American species of Dryopteris and along with ostrich fern it is one of the largest ferns in eastern North America. Specimens are known with fronds six feet (1.8 meters) tall. D. goldiana hybridizes with many other species of Dryopteris and the hybrids tend to be larger than the pure species. It was named by William Hooker in honor of its discoverer, John Goldie.
