Haplopteris is a genus of vittarioid ferns, a member of subfamily Vittarioideae and family Pteridaceae.

The rhizome has a distinct upper and lower side, lacking radial symmetry, a characteristic that separates it from Radiovittaria.

Leaves are borne in two ranks in a single plane, and are usually simple, occasionally forked.

[1] The genus was first described by Carl Borivoj Presl in 1836, separating it from Pteris sensu Bory.

Presl transferred Bory's Pteris scolopendrina to the genus as the type species.

[2] Molecular phylogenetic studies have shown that the type species of Monogramma is embedded in Haplopteris.
