Fraser's musk shrew (Crocidura poensis) is a species of mammal in the family Soricidae.

Its exact definition is unclear; the karyotype comes from Ivory Coast but not from Equatorial Guinea, which is given as the type locality.

Its range extends from Guinea, Sierra Leone and Liberia through Ivory Coast, Ghana and Nigeria to Cameroon.

Fraser's musk shrew is also present on the islands of São Tomé and Príncipe, located in the Gulf of Guinea.
