Thelypteridaceae is a family of about 900 species of ferns in the order Polypodiales. In the Pteridophyte Phylogeny Group classification of 2016, it is placed in the suborder Aspleniineae. Alternatively, the family may be submerged in a very broadly defined family Aspleniaceae as the subfamily Thelypteridoideae.
Thelypteris is a genus of ferns in the subfamily Thelypteridoideae, family Thelypteridaceae, order Polypodiales. Two radically different circumscriptions of the genus are in use as of January 2020. In the Pteridophyte Phylogeny Group classification of 2016, the genus is a very small one with about two species. In other approaches, the genus is the only one in the subfamily Thelypteridoideae, and so includes between 875 and 1083 species.

Thelypteris palustris, the marsh fern, or eastern marsh fern, is a species of fern native to eastern North America and across Eurasia. It prefers to grow in marshy situations in full sun. The species epithet palustris is Latin for "of the marsh" and indicates its common habitat. It is the only known host plant for Fagitana littera, the marsh fern moth.
Christella normalis, synonym Thelypteris kunthii, sometimes known as Kunth's maiden fern or southern shield fern, is the most common of the maiden ferns in the southeastern United States south of the fall line. It ranges westward to eastern Texas. It usually grows in moist to dry terrestrial situations, but can also be epipetric. It often grows as a greenhouse escape in areas north of its usual range.
Parathelypteris nevadensis, synonym Thelypteris nevadensis, is a species of fern known by the common names Sierra marsh fern, Sierra wood fern, and Nevada marsh fern. It is native to western North America from British Columbia to the mountains of northern California, where it grows in moist wooded areas, streamsides, meadows, and seeps. It is known from two locations in Idaho, as well. Despite its name it is not found in Nevada, rather, it was named for the Sierra Nevada, where it does occur in the northern mountains. It produces a dense cluster of long, feathery leaves which may be up to a meter long. It is rhizomatous and it sometimes forms colonies. The leaves die back in winter. Each leaf is made up of leaflets lined with smaller segments. The undersides are glandular and resinous and sometimes hairy.
Christella puberula, synonym Thelypteris puberula, is a species of fern known by the common name showy maiden fern. The variety Ch. puberula var. sonorensis is known by the common name Sonoran maiden fern.
Amauropelta inabonensis, synonym Thelypteris inabonensis, is a rare species of fern known by the common name cordillera maiden fern. It is endemic to Puerto Rico, where it is known from only two localities: at the headwaters of Río Inabón and at the Toro Negro State Forest. It is a federally listed endangered species of the United States.
Goniopteris verecunda, synonym Thelypteris verecunda, is a rare species of fern known by the common name Barrio Charcas maiden fern. It is endemic to Puerto Rico, where it is known from only three localities. It is a federally listed endangered species of the United States.

Coryphopteris simulata, synonym Thelypteris simulata, is a species of fern native to the Northeastern United States. It is known by two common names: bog-fern and Massachusetts fern. It is often confused with the silvery spleenwort, New York fern, and the marsh fern due to similarities in shape and size.
Stegnogramma is a genus of ferns in the subfamily Thelypteridoideae of the family Thelypteridaceae in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink Stegnogramma into a very broadly defined genus Thelypteris.
Stegnogramma burksiorum, synonym Thelypteris burksiorum, the Alabama maiden fern, is a fern species in the family Thelypteridaceae. It is closely related to Stegnogramma pilosa and has been treated as the variety alabamensis of that species; the two have also been treated as a species complex. Stegnogramma burksiorum is native to Alabama in the United States.
Thelypteris ovata, the ovate marsh fern or ovate maiden fern, is a species of fern in the Thelypteridaceae family. Native to the southeastern United States, in Georgia it can be found in the Coastal Plain.
