Struthiopteris spicant, syn. Blechnum spicant, is a species of fern in the family Blechnaceae, known by the common names hard-fern{{BSBI 2007|access-date=2014-10-17 }} or deer fern. It is native to Europe, western Asia, northern Africa, and western North America. Like some other species in the family Blechnaceae, it has two types of leaves. The sterile leaves have flat, wavy-margined leaflets 5 to 8 millimeters wide, while the fertile leaves have much narrower leaflets, each with two thick rows of sori on the underside.
The Latin specific epithet spicant is of uncertain origin, possibly referring to a tufted or spiky habit.{{cite book |last=Harrison |first=Lorraine |title=RHS Latin for Gardeners |year=2012 |publisher=Mitchell Beazley |location=United Kingdom |isbn=978-1845337315 }}
