'''''Orthogoniosaurus''''' (meaning "straight angled [[lizard]]", referring to the straight posterior edge of its [[holotype|type]] [[tooth]]) was a [[genus]] of [[theropod]] [[dinosaur]] from the [[Maastrichtian|late Maastrichtian]]-age [[Upper Cretaceous]] [[Lameta Formation]] of [[Jabalpur]], [[India]]. It is based on one small, fragmentary tooth (preserved section 27 mm (1.1 in) long).<ref name=HDG31>Das-Gupta, H.C. (1931). On a new theropod dinosaur (''Orthogoniosaurus matleyi'', n. gen. et n. sp.) from the Lameta beds of Jubbulpore. ''Journal of the Asiatic Society of Bengal, New Series'' '''16'''(20):367-369.</ref>

Because it is the earliest published name for a Lameta theropod, it has sometimes been used as a synonym for other contemporaneous theropods, such as ''[[Indosaurus]]'' and ''[[Indosuchus]]''.<ref name=ASR56>[[Alfred Sherwood Romer|Romer, A.S.]] (1956). ''Osteology of the Reptiles''. University of Chicago Press:Chicago 1-772. {{ISBN|0-89464-985-X}}</ref> As a tooth taxon, however, such usage has been discouraged.<ref name=ADW64>Walker, A.D. (1964).

''Philosophical Transactions of the Royal Society of London, Series B'' '''248'''(744):53-134.</ref> [[Ralph Molnar]] in 1990 noted that the form of the tooth was most like teeth from the rear of theropod jaws, although the lack of serrations on the leading edge was unusual.<ref name=RM90>Molnar, R.E.
