The genus Mus or typical mice refers to a specific genus of muroid rodents, all typically called mice, though the term can be used for other rodents. They are the only members of the tribe Murini. However, the term mouse can also be applied to species outside of this genus.

A mouse is a small rodent. Characteristically, mice are known to have a pointed snout, small rounded ears, a body-length scaly tail, and a high breeding rate. The best known mouse species is the common house mouse. Mice are also popular as pets. In some places, certain kinds of field mice are locally common. They are known to invade homes for food and shelter.
