The list of freshwater gastropods of Bulgaria, with data on their distribution, ecology and conservation status, was based on a critical overview of all available sources and unpublished materials. The total number of freshwater snail species hitherto recorded from Bulgaria is 120. Three species are regarded as extinct, two species were found only as subfossil remains. The most diverse families are Hydrobiidae (67 species), Planorbidae (15), and Lymnaeidae (11). The remaining families are represented by 1 to 4 species. Zoogeographical, ecological and conservation data are discussed.
