孔耐蜥属（学名Kuehneosaurus）又名滑翔蜥、孔耐龙、库恩奥龙，是种晚三叠纪的爬行动物，发现于英国。孔耐蜥大约72公分长，拥有从身体突出14.3公分长的肋骨，之间有皮膜连接，可能是用来在树间滑翔，就像现代的飞蜥。孔耐蜥属于孔耐蜥科，是一个滑翔爬行动物，属于鳞龙形下纲，该下纲也包含了现代蜥蜴与喙头蜥。孔耐鳄（Kuehneosuchus）是其近亲，两者可能是同一物种，或是两性异形。

气动力学研究指出孔耐蜥可能不是滑翔者，而是利用肋骨与皮膜在树间降落。在2008年的研究指出当孔耐蜥以45度降落时，时速可达每秒10到12公尺。飞行时的俯仰动作可由舌骨上的皮瓣来控制，如同现代的飞蜥。

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.
