铗龙属（学名：Labidosaurus）是种史前爬行动物，生存于二叠纪，身长约75公分。化石发现于美国德州。

铗龙非常原始，身体笨重，外形类似蜥蜴，头部大。不同于其他大鼻龙科，铗龙具有锐利的单排圆锥状牙齿，被推测是杂食性动物，以昆虫或其他有硬壳的动物为食，或者是坚硬的植物。

在2001年，一个铗龙下颌被发现曾有骨头发炎的病症。这是已知最早被发现有骨髓炎的陆地脊椎动物。科学家推测，这可能因为齿骨的牙齿断裂，导致牙髓腔接触到细菌。铗龙与其他高端型大鼻龙科动物，牙齿深植于颌部骨头，因此牠们的牙齿替换时，速度较慢。因此断裂牙齿可能长期接触到口腔里的细菌，造成感染。

Labidosaurus is an extinct genus of anapsid reptile from the Permian period of North America. Fossils have been discovered in Texas.

It was heavily built, resembling a lizard with a large head, and measuring about 75 centimetres (30 in) long. Unlike many other captorhinids it had a single row of sharp, conical teeth in its jaws, and its dietary habits are assumed to have been omnivorous.
