Tylomelania is a genus of freshwater snails which have an operculum, aquatic gastropod mollusks in the family Pachychilidae. In the aquarium hobby, snails from this genus are commonly known as "rabbit snails" (not to be confused with sea hares).

A sister group (the closest relative) of Tylomelania is genus Pseudopotamis (two species living on the Torres Strait Islands). Tylomelania and Pseudopotamis split in the Middle Miocene c. 19.5 Mya.
