Sceptridium is a genus of seedless vascular plants, closely allied to (and previously often included in) the genus Botrychium (moonworts) and also closely related to the genus Botrypus (grape-ferns).

These plants are small with fleshy roots, and reproduce by spores shed into the air. They differ from the moonworts in having at least some sterile fronds (all fronds in Botrychium are spore-bearing), and in the fronds being bi- or tri-pinnate (Botrychium are single pinnate, or rarely bipinnate); and from Botrypus in being evergreen (Botrypus are deciduous) and having the non-spore-bearing part of the frond long-stalked (short-stalked in Botrypus).
