Beddomeia fultoni (B. fultoni) is a species of small freshwater snail belonging to the family Tateidae.

The species is endemic to Australia. Commonly known as Farnhams Creek hydrobiid snail, the species used to belong to the family Hydrobiidae sensu lato (s.l.)  and is listed as one of 37 threatened Beddomeia species on the Tasmanian Threatened Species Protection Act 1995.

Found within north-western Tasmania, the species has a somewhat small range. Previously, they have only been identified in sites within six different streams which are separated by a maximum of 4 km. A large portion of the Beddomeia species, including B. fultoni fall into the category of narrow-range endemic species. These narrow-range taxa are generally poorly reserved due to limitations caused by small distributions, size, mobility, biogeographical boundaries and highly specific habitat requirements. Habitat disturbance from agricultural and domestic land use, climate change and invasive species are currently the principal threats contributing to the vulnerability of the species.
