Bithynia is a genus of small freshwater snails with an operculum, aquatic prosobranch gastropod mollusks in the family Bithyniidae.

The diploid chromosome number of Bithynia sp. from Egypt is 2n=32.

Lake Skadar with 5 species of Bithynia is a biodiversity hotspot of Bithynia evolution.

Glöer (2002) recognized four subgenera Bithynia, Codiella, Neumayria and Parafossarulus within European species. He reassigned two European extinct species of Parafossarulus into a subgenus of the genus Bithynia, but the genus Parafossarulus is generally accepted for the Asian species. The subgenus Digoniostoma is also recognized for Asian species.

Subgenera and species within the genus Bithynia include:

Subgenus Bithynia Leach, 1818

Subgenus Codiella Locard, 1894

Subgenus Neumayria De Stefani, 1887

Subgenus Digoniostoma Annandale, 1920

Subgenus Incertae sedis
