'''Bithyniidae''' is a family of small freshwater snails with an operculum, aquatic gastropod molluscs in the Littorinimorpha.<ref name="WoRMS">Bouchet, P.; Gofas, S. (2015). Bithyniidae Gray, 1857. In: MolluscaBase (2015). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=182697 on 2016-02-28</ref>
Their shells are very small and often colored. They are characterized by a calcareous operculum, a lobe on the upper surface of the neck. The ctenidium, the respiratory gill-comb, is very broad. They have a ciliary feeding habit. The kidney has a large extension towards the mantle.<ref name="Lilly">{{cite journal | author=Lilly, M.M.| title=The mode of life and the structure and functioning of the reproductive ducts of Bithynia tentaculata (L.)| journal=Proceedings of the Malacological Society of London| year=1953| volume=30| issue=4–5| pages=87–110}}</ref>
