Cystopteridaceae is a family of ferns in the order Polypodiales. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family is placed in the suborder Aspleniineae of the order Polypodiales, and includes three genera.^[2] Alternatively, it may be treated as the subfamily Cystopteridoideae of a very broadly defined family Aspleniaceae.^[3]

Cystopteridaceae are small or medium-sized ferns in forests and crevices.^[4] They generally have thin laminae, and small, round, naked sori.
