The Lomariopsidaceae is a family of ferns with a largely tropical distribution.

In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family is placed in the suborder Polypodiineae (eupolypods I) of the order Polypodiales.

[1] Alternatively, it may be treated as the subfamily Lomariopsidoideae of a very broadly defined family Polypodiaceae sensu lato.

[2][3] The Pteridophyte Phylogeny Group classification of 2016 (PPG I) included four genera.

Didymochlaenaceae Hypodematiaceae Dryopteridaceae Nephrolepidaceae Lomariopsidaceae Tectariaceae Oleandraceae Davalliaceae Polypodiaceae Dryopolystichum Cyclopeltis Dracoglossum Lomariopsis
