Teleosaurus (from , 'perfect' and , 'lizard') is an extinct genus of teleosaurid crocodyliform found in the Middle Jurassic Calcaire de Caen Formation of France. It was approximately in length. The holotype is MNHN AC 8746, a quarter of a skull and other associated postcranial remains, while other fragmentary specimens are known. The type species is T. cadomensis, but a second species, T. geoffroyi may also exist. It was previously considered a wastebasket taxon, with many other remains assigned to the genus.

==History== thumb|left|Skull illustration left|thumb|Dorsal osteoderms (NHMUK PV R 4207) of T. cadomensis from Normandy, which have been in the collection of the [[Field Museum of Natural History since 1914]] Teleosaur remains have been known to science since at least 1758, although at first scientists believed the remains belonged to extinct crocodiles and alligators, and remains that have at one point in time been attributed to Teleosaurus (and Steneosaurus) have been known to science since at least 1800. The holotype was discovered during the early 19th century by Pierre Tesson before he traded it with Lamoroux. Teleosaurus was briefly noted on by Jean Vincent Félix Lamouroux in 1820 as Crocodilus cadomensis and then he sent the specimen to Georges Cuvier. It was fully described by Cuvier in 1824, but it was not published until a year later by Étienne Geoffroy Saint-Hilaire.
