Viscaria is a genus of flowering plants in the family Caryophyllaceae, native to Canada, Greenland, Iceland, Europe, Kazakhstan, and western Siberia. Molecular studies attempting to resolve relationships in the tribe Sileneae have found that Viscaria is closely genetically related to the genus Atocion, but is quite distinct from it morphologically.{{cite journal |title= Pericarp structure in some species in the tribe Sileneae DC.
