Beddomeia hallae, also known as Buttons Rivulet hydrobiid snail, is a species of small freshwater snail that is endemic to Australia. The species is an aquatic operculate gastropod mollusk in the family Hydrobiidae. Beddomeia hallae belongs to the genus Beddomeia, which is the largest group in the family Hydrobiidae, consisting of 47 species. In the Threatened Species Protection Act 1995, this species is one of the 37 Beddomeia species listed as endangered, however, on the International Union for Conservation of Nature Red List, the species is listed as vulnerable. Found in Tasmania, in the streams of Buttons Rivulet and Castra Rivulet, Beddomeia hallae is sighted in its natural habitat amongst wood, leaves and under stones. Nonetheless, the Beddomeia species including Beddomeia hallae are geographically isolated, existing within restricted ranges.

Beddomeia hallae's survival as a species is threatened by agricultural clearing, forestry practices, mining and impoundment construction, resulting in habitat degradation or modification. However, for Beddomeia hallae, the main limiting factors are agricultural land practices and production forestry. To manage the threatened status of the Beddomeia hallae species, management objectives use the precautionary principle in preventing the degradation or loss of habitat containing existing populations, as well as identifying where new subpopulations occur, improving the reservation status and increasing public awareness of this species. Freshwater hydrobiid snails depend on their habitat for survival, therefore the protection of the habitat in the long-term is important to the survival of this species. Beddomeia hallae may experience difficulty in dispersing outside their immediate habitat, which can affect the survival of this species.
