See text Bertiniidae Jousseaume, 1883 Nacellidae is a taxonomic family of sea snails or true limpets, marine gastropod molluscs in the subclass Patellogastropoda.

[2][3] Nacellidae was the only family in the superfamily Nacelloidea as described by Bouchet & Rocroi (2005),.

[2] However a molecular phylogenetic study of Patellogastropoda by Nakano & Ozawa (2007) found that Nacellidae was recovered within Lottioidea, as shown in the following cladogram:[4] Lottiidae (including Acmaea and Niveotectura) Pectinodontidae Lepetidae Nacellidae Patellidae Eoacmaeidae As a result Nacellidae was moved to Lottioidea in the taxonomic revision of Bouchet et al (2017).

[3] More recently, a recent phylogenomic study found Nacellidae as a sister to Patellidae, which suggests that Nacellidae should be transferred to Patelloidea.

[5][6] Genera within the family Nacellidae include:[6]
