Dormice are Old World mammals in the family Gliridae, part of the rodent (Rodentia) order. (This family is also variously called Myoxidae or Muscardinidae by different taxonomists). Dormice are mostly found in Europe, although some live in Africa and Asia. Dormice were considered a delicacy in ancient Rome.

They are small for rodents, with a typical length of about 2-3" (70 mm). Dormice typically feed on fruits, berries, flowers, nuts and insects. They are largely but not exclusively arboreal and nocturnal animals.

One of the most notable characteristics of those dormice that live in temperate zones is hibernation. Dormice can hibernate six months out of the year, or even longer if the weather remains sufficiently cool, sometimes waking for brief periods to eat food they had previously stored nearby. It is from this trait that they got their name, which comes from Anglo-Norman dormeus, which means "sleepy (one)"; the word was later altered by folk etymology to resemble word "mouse". The sleepy behaviour of the Dormouse character in Lewis Carroll's Alice's Adventures in Wonderland also attests to this trait.

Dormice breed once or twice a year, with four being the typical size of a litter. They can live for as long as five years.

Currently, the earliest fossil evidence of dormouse species in Europe is placed in the middle Eocene. They appear in Africa in the upper Miocene and only relatively recently in Asia. Many types of extinct dormouse species have been identified. In the current (Holocene) epoch, the family consists of 28 species, in three subfamilies and (arguably) 9 genera:
