Valvatidae, the valve snails, is a taxonomic family of very small freshwater snails with an operculum, aquatic gastropod mollusks.


The family Valvatidae has no subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).


The type genus of this family is Valvata O.F. Müller, 1774.

Genera in the family Valvatidae include:


Snails in the family Valvatidae are useful for measuring water quality as biological indicators. According to the Biological monitoring working party they have a score of 3, which means that they have quite a high tolerance to pollutants.
