A dormouse is a rodent of the family Gliridae. Dormice are nocturnal animals found in Africa, Asia, and Europe, and are particularly known for their long periods of hibernation.

The English name of the species derived from the French "dormeuse" (from stem of dormir 'to sleep').

Dormice are small rodents, with body lengths between 6 and 19 cm (2.4 and 7.5 in), and weights between 15 and 180 g (0.53 and 6.35 oz). They are generally mouse-like in appearance, but with furred, rather than scaly, tails. They are largely arboreal, agile, and well adapted to climbing. Dormice have an excellent sense of hearing and signal each other with a variety of vocalisations.

Dormice are omnivorous, and typically feed on berries, flowers, fruits, insects, and nuts. They are unique among rodents in that they lack a cecum, a part of the gut used in other species to ferment vegetable matter.

The edible dormouse ("Glis glis") was considered a delicacy in ancient Rome, either as a savoury appetizer or as a dessert (dipped in honey and poppy seeds). The Romans used a special kind of enclosure, a glirarium, to raise and fatten dormice for the table. It is still considered a delicacy in Slovenia and in several places in Croatia, namely Lika, and the islands of Hvar and Brač. Dormouse fat was believed by the Elizabethans to induce sleep since the animal put on fat before hibernating.
