"Titanosaurus" (meaning 'titanic reptile' - named after the mythological 'Titans', deities of Ancient Greece) is a genus of sauropod dinosaur. It is known from the Maastrichtian (Upper Cretaceous) Lameta Formation of India. Species assigned to "Titanosaurus" are also known from southern Europe and South America.

"Titanosaurus" was 9-12 metres (30-40 ft) long and weighed about 13 tons. "Titanosaurus" has traditionally been treated as a "wastebin taxon" for poorly preserved sauropod remains that demonstrate a distinctive vertebrae anatomy. The original "Titanosaurus" remains consist only of limb bones and a few vertebrae that have these characteristics. However, discoveries of more and better-preserved titanosaur species have shown that these once distinctive features are in fact widespread across many genera. Therefore, "Titanosaurus" itself is considered a "nomen dubium" ("dubious name") by most paleontologists, since the original "Titanosaurus" specimens cannot be distinguished from those of related animals.

The most well-known species of "Titanosaurus", "Titanosaurus" "colberti", has been renamed "Isisaurus".
