Xinjiangovenator, meaning "Xinjiang hunter," is a genus of coelurosaurian dinosaurs, potentially belonging to the Maniraptora group. These dinosaurs existed during the Early Cretaceous period, spanning from the Valanginian to Albian stages. The fossilized remains of Xinjiangovenator were discovered in the Lianmuqin Formation of Wuerho, Xinjiang, China, and were initially documented by Dong Zhiming in 1973. This genus is primarily based on a single specimen, which consists of an articulated partial right lower leg, incorporating the tibia, three fibula fragments, as well as the calcaneum and astragalus bones.

Fossils initially assigned to the genus Phaedrolosaurus were later reevaluated. Originally, Phaedrolosaurus was described based on a single tooth, with additional lower limb bones attributed to the genus because they were discovered in the same fossil-bearing formation. However, in 2005, Rauhut and Xu separated these remains from the tooth. They argued that there was no direct evidence linking these bones, apart from their proximity in the same formation. As a result, Phaedrolosaurus is currently known only from a single tooth, while Xinjiangovenator is represented by lower leg bones.

There is limited information available about Xinjiangovenator; however, it is inferred to have been a carnivorous dinosaur that likely preyed on smaller creatures and other dinosaurs.
