Deltadromeus (meaning "delta runner") is a genus of theropod dinosaur from the Aoufous Formation of Morocco.^[1]

It had long, unusually slender hind limbs for its size, suggesting that it was a swift runner.^[1] The skull is not known. One fossil specimen of a single species (D. agilis, or "agile delta runner") has been described, found in the Kem Kem Beds, which date to the mid-Cretaceous Period (mid-Cenomanian age), about 95 million years ago. It may be a junior synonym of the contemporary Bahariasaurus.^[2] The classification of Deltadromeus has been in flux since its original description. In 2016, a South American theropod known as Gualicho shinyae was found to possess many similarities with Deltadromeus. Depending on the phylogenetic position of Gualicho, Deltadromeus may have been a neovenatorid carnosaur, a tyrannosauroid, or a basal coelurosaur if its close relation to Gualicho is legitimate.^[3]^[4]^[5] Other studies have considered it a ceratosaurian, more specifically a member of the family Noasauridae.^[6]^[7]^[8]^[9]
