Stanley's white-toothed shrew, Crocidura stanleyi, is a species of mammal in the family Soricidae. It is endemic to Ethiopia. The species was named after scientist Bill Stanley, whose fieldwork in 2015 garnered the holotype specimen that was eventually used to formally define the species. The species was found in the Ethiopian highlands.
The species is described as one of the smallest mammals on Earth, as it weighs just 3 grams which is equivalent to the weight of an average sugar cube. The species is 5 centimeters in length.
