Nectosaurus is a genus of thalattosaur (marine diapsid reptiles) which lived during the Late Triassic in what is now California. The type and only known species, Nectosaurus halius, was found in the Hosselkus Limestone and described by John C. Merriam in 1905, making it one of the first thalattosaurians known (along with Thalattosaurus).
