Zupaysaurus (/ˌzuːpeɪˈsɔːrəs/; "ZOO-pay-SAWR-us") is an extinct genus of early theropod dinosaur which lived during the Norian stage of the Late Triassic in what is now Argentina. Fossils of the dinosaur were found in the Los Colorados Formation of the Ischigualasto-Villa Unión Basin in northwestern Argentina.
Although a full skeleton has not yet been discovered, Zupaysaurus can be considered a bipedal predator, up to 4 metres (13 ft) long. Originally described as having a pair of tall narrow crests on its skull, a later study argued that the "crests" are misplaced bones, and that Zupaysaurus probably had low ridges along the edge of its snout instead.
