The gymnure, also called a hairy hedgehog or moonrat, is a type of mammal belonging to the subfamily Galericinae, in the family Erinaceidae and the order Eulipotyphla. Gymnures resemble rats but are not closely related as they are not rodents; they are instead closely related to hedgehogs, which also belong to Erinaceidae. They are thought to have appeared in Eastern Asia before their closest relatives, and changed little from the original ancestor, which is thought to have been also the ancestor of the shrews.
Deinogalerix is an extinct genus of gymnure which lived in Italy in the Late Miocene, 7-10 million years ago. The genus was apparently endemic to what was then the island of Gargano, which is now a peninsula. The first specimens of Deinogalerix were first described in 1972.

The moonrat is a southeast Asian species of mammal in the family Erinaceidae. It is the only species in the genus Echinosorex. The moonrat is a fairly small, primarily carnivorous animal which, despite its name, is not closely related to rats or other rodents. The scientific name is sometimes given as Echinosorex gymnurus, but this is incorrect.

The Hainan gymnure or Hainan moonrat is a species of mammal in the family Erinaceidae. Its natural habitat is subtropical or tropical dry forests. It was thought to be endemic to the island of Hainan, China where it is threatened due to habitat loss, but in 2018 was found to also occur in, and be rather common, within Northern Vietnam.
Hylomys is a small genus of the family Erinaceidae. Hylomys species, like all species in the subfamily Galericinae, are known as gymnures or moonrats. Their closest relatives include the fossil Lantanotherium and Thaiagymnura and the living Neotetracus and Neohylomys.
