The Inyo shrew (Sorex tenellus) is a species of shrew found in the western United States. Not much is known about its behavioral and reproductive habits. It is small, very similar in appearance to the related dwarf shrew (Sorex nanus), but smaller and paler. It can be found in many different habitats, from rocky, mountainous regions to wetlands and riparian areas. While barely studied, their population is believed to be stable and not under any threat.
