The western mouse or walyadji refers to Pseudomys occidentalis, a species of rodent in the family Muridae. Once widespread across a larger range, it has become restricted to around ten reserves of remnant bushland in Southwest Australia and declared near threatened by extinction. They are small and robust mice that live in burrows in sandy soil, venturing out at night to forage in nearby area. Assigned to a diverse and poorly resolved genus, Pseudomys, the describing author allied the species to a subgeneric classification as Gyomys.

The term walyadji is used to refer to the species, but this word does not appear in a literature review of Noongar language names for mammals of the region.
