Bahariasaurus (meaning "Bahariya lizard") is an enigmatic genus of large theropod dinosaur. The genus contains a single species, Bahariasaurus ingens, which was found in North African rock layers dating to the Cenomanian age of the Late Cretaceous. The only fossils confidently assigned to Bahariasaurus were found in the Bahariya Formation of the Bahariya Oasis in Egypt by Ernst Stromer. This material was destroyed during a World War II bombing raid, with the same raid also destroying the holotypes of Spinosaurus, Aegyptosaurus, and other other animals found in the Bahariya Formation.

Bahariasaurus is among the largest known theropods, estimated at 11–12 metres (36–39 ft) long and around 4 tonnes (3.9 long tons; 4.4 short tons) in weight. This approaches the size of other large theropods such as Tyrannosaurus rex and the contemporaneous Carcharodontosaurus. The exact phylogenetic placement of Bahariasaurus has been debated. Some research has proposed close affiinities or even synonymy of Bahariasaurus and the coeval Deltadromeus.
