Proaigialosaurus is an extinct genus of semi-aquatic diapsid reptile. The genus was erected by Kuhn (1958), based upon skull fragments, which have since been lost.^[1]

Generally considered the oldest specimen of the lizard family Aigialosauridae, others have considered it to be a pleurosaurid, a marine sphenodontian (the order to which the extant Tuatara belongs).^[2]

Proaigialosaurus was discovered in the Solnhofen limestone formation of Bavaria, Germany.^[2] It was small (less than a metre long).^[2]
