Marattiidae is a subclass of class Polypodiopsida (ferns). This subclass comprises a single fern order, Marattiales, and family, Marattiaceae. It is equivalent to the class Marattiopsida in previous treatments, including Smith et al., 2006.

Taxonomy

Marattiidae is one of four subclasses of class Polypodiopsida (ferns), to which it is related as shown in this cladogram, being a sister group to Polypodiidae. The first three small subclasses are sometimes informally referred to as eusporangiate ferns, in contrast to the largest subclass, Polypodiidae or leptosporangiate ferns.

Polypodiopsida	Equisetidae Ophioglossidae Marattiidae Polypodiidae

In earlier classifications such as Smith et al. (2006) it was known as Marattiopsida, but was renamed Marattiidae in that of Mark W. Chase and James L. Reveal and subsequent systems such as Christenhusz et al. (2011) and the Pteridophyte Phylogeny Group (2016). In that system, Marattiidae is monotypic has one order, one family, six genera, and an estimated 111 species.
