Kuehneosaurus is an extinct genus of Late Triassic kuehneosaurid reptile known from the Late Triassic (Norian stage) of southwest England. It was named by P. L. Robinson in 1962 and the type and only species is Kuehneosaurus latus. Measuring 72 centimetres long (2.3 feet), it had "wings" formed from ribs which jutted out from its body by as much as 14.3 cm, connected by a membrane which allowed it to slow its descent when jumping from trees. It is a member of a family of gliding reptiles, the Kuehneosauridae, within the larger group Lepidosauromorpha, which also contains modern lizards and tuatara.
