The Nederlandse Malacologische Vereniging (NMV), known in English as the Netherlands Malacological Society or the Dutch Malacological Society, is a non-profit organisation based in the Netherlands. It is a society devoted to malacology (the study of molluscs) as well as conchology (the study of mollusc shells). The NMV was founded in 1934, and the members include both professionals and amateurs. The NMV created a European malacological society which later became the global society Unitas Malacologica. The society publishes three periodicals: the scientific journal Basteria, Vita Malacologica (a twice-annual themed supplement to Basteria published only in English) and the NMV news journal Spirula (formerly known as Correspondentieblad).
