Sceptridium is a genus of seedless vascular plants in the family Ophioglossaceae, closely allied to (and often included as a subgenus of) the genus Botrychium (the moonworts and grapeferns). It is also closely related to the genus Botrypus (the rattlesnake fern, often treated as the subgenus Osmundopteris under Botrychium). Sceptridium species are commonly called the grape-ferns.
