This article is about the Squamata order of reptiles. For the Roman scale armour see: Lorica squamata.

Squamata (scaled reptiles) is the largest recent order of reptiles, including lizards and snakes. Members of the order are distinguished by their skins, which bear horny scales or shields. They also possess movable quadrate bones, making it possible to move the upper jaw relative to the braincase. This is particularly visible in snakes, which are able to detach their jaws entirely to accommodate very large prey items. The male members of the group Squamata are the only vertebrates with a hemipenis. This is also the only reptile group where we can find both viviparous and ovoviviparous species, as well as the usual oviparous reptiles.

Classically, the order is divided into three suborders:
