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.

Classically, the order is divided into three suborders:

Of these, the lizards form a paraphyletic group. In newer classifications the name Sauria is used for reptiles and birds in general, and the Squamata are divided differently:

The exact relationships within these two suborders are not entirely certain yet.da:Slanger og øgler de:Schuppenkriechtiere li:Squamata nl:Squamata pt:Escamados fi:Suomumatelijat sv:Fjällbärande kräldjur zh:有鱗目
