Polypodiaceae is a family of ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family includes around 65 genera and an estimated 1,650 species and is placed in the order Polypodiales, suborder Polypodiineae.

The subfamilies are treated as tribes in other systems. Mabberley, in 2008, treated all of Polypodiaceae except for the Platycerioideae (Platycerium and Pyrrosia) and the grammitid ferns, which he placed in Grammitidaceae, as the subfamily Polypodioideae, which he then divided into six tribes, four of which correspond to PPG I subfamilies (Drynarieae, Loxogrammeae, Microsoreae and Polypodieae) and others of which have been submerged (Selligueeae, now within Drynarioideae, and Lepisoreae, now within Microsoroideae).|
