''Pentarhizidium'' is a genus of two Asian fern species. These species have formerly been included in ''
Matteuccia'' or ''
Onoclea''.
Recent genetic analysis has determined that these two species form a discrete clade that is basal to the rest of this fern group, and so have been located in their own genus. ''P. orientale'' is sometimes grown as a garden plant.
