'Indian lizard') is a genus of dubious carnivorous theropod dinosaur that lived in what is now India, about 69 to 66 million years ago during the Maastrichtian division of the Late Cretaceous.

This species now also includes Megalosaurus matleyi; confusingly, the dubious tooth taxon Orthogoniosaurus shares the same specific name but is based on different material.

[4] The parietal of the frontal-parietal region is broad whereas the lower surface of the frontal is wide, the transverse crest lies above and behind the orbit.

Originally assigned by Huene to the Allosauridae, Indosaurus is today considered a member of the Abelisauridae family.

[7] It shows similarities to the other Abelisaurids from India, such as Rajasaurus and Rahiolisaurus, and is hence usually placed within Abelisauridae, though the fragmentary nature for this taxon makes it difficult to recognize it's exact taxonomic validity.

This was to separate Arcovenator, Majungasaurus, Indosaurus, Rahiolisaurus, and Rajasaurus from South American abelisaurids based on physical characteristics such as elongated antorbital fenestrae in front of the eye sockets, and a sagittal crest that widens into a triangular surface towards the front of the head.
