Pleurocera is a genus of freshwater snails with an operculum, gastropod mollusks in the family Pleuroceridae. Pleurocera is the type genus of that family. All mambers of the genus Pleurocera are native to eastern North America. Most inhabit the larger rivers, but many also thrive in reservoirs. All are thick-walled high-spired snails, and some may attain over 4 cm in length. Larger species may develop sculpturing and a small siphonal canal or notch at the base of the aperture. The animal usually has a gray or brown coloration, commonly speckled with orange. Opercula are paucispiral and corneous, but may be vestigial in some species, not completely closing the aperture.
Species within the genus Pleurocera include:
