Batillariidae, common name batillariids or mudcreepers, are a family of marine, cerithioidean gastropod molluscs in thesuperfamily Cerithioidea.

They consist of 14 living species, classified in six to eight genera.

According to the taxonomy of the Gastropoda by Bouchet & Rocroi (2005) the family Batillariidae has no subfamilies. However, a recent molecular study has found that the Batillariidae as traditionally conceived are not monophyletic. The Neotropical genera Lampanella and Rhinocoryne are sister to the Planaxidae. The monophyletic Batillariidae sensu stricto are restricted to the northwestern Pacific and Australasia.

A revised generic classification has been suggested that is consistent with a molecular phylogenetic hypothesis. Accordingly, within the Batillariidae four genera Batillaria, Pyrazus, Velacumantus and Zeacumantus have been recognized. This delimitation of taxa is consistent with a revised definition of the family based on shell characters.
