Calvatia is a genus of puffball mushrooms that includes the spectacular giant puffball C. gigantea. It was formerly classified within the now-obsolete order Lycoperdales, which, following a restructuring of fungal taxonomy brought about by molecular phylogeny, has been split; the puffballs, Calvatia spp. are now placed in the family Agaricaceae of the order Agaricales.
