Semisulcospiridae, common name semisulcospirids, is a family of freshwater snails, aquatic gilled gastropod mollusks with an operculum, in the superfamily Cerithioidea.
Semisulcospiridae diversified from the Pleuroceridae about 90 millions years ago, in the Cretaceous.[4]

The family Semisulcospiridae occurs in western North America, the Far East of Russia, Korea, Japan, China and Vietnam.
The family Semisulcospiridae was introduced as just a name by Morrison (1952),[1] but without a diagnosis of the taxon. It is a valid taxon however, because its name has been used as valid.
According to the taxonomy of Bouchet & Rocroi (2005), Semisulcospiridae was a subfamily within the family Pleuroceridae.[3]
The subfamily Semisulcospirinae within the Pleuroceridae was elevated to family level as Semisulcospiridae by Strong & Köhler (2009).[4]
Genera within the family Pleuroceridae include:
