Marattia is a small genus of primitive, large, fleshy eusporangiate ferns. It is the type genus of the family Marattiaceae, order Marattiales and class Marattiopsida.[1] Formerly considered to be a much larger genus, genetic analysis has shown that Marattia in the broad sense was paraphyletic, and subsequently the genera Ptisana and Eupodium were split off.[2][3] Except for one species in Hawaii, the genus is neotropical.

The plants are large and terrestrial, with more or less erect rhizomes and fronds being 2-5 times pinnate. Sporangia are fused into synangia, and spores are monolete.

Basal chromosome count is 2n=80. The type species is M. alata.
