Dzharaonyx (meaning "Dzharakuduk claw", named after the type locality) is a genus of alvarezsaurid theropod dinosaur from the Late Cretaceous Bissekty Formation of Uzbekistan. The type species is Dzharaonyx eski; eski being an Uzbek word for "old". [1]
Dzharaonyx is known from a series of disassociated but well-preserved postcranial material. The form of the humerus is intermediate between that of Patagonykus and Mononykus. [1]
Phylogenetic analysis places Dzharaonyx in a polytomy including other Asian members of Parvicursorinae. This makes it the oldest parvicursorine known to date. [1]

Dzharaonyx lived in the Bissekty Formation, which has been intensively studied in recent years. It represents a brackish environment. [3] It coexisted with larger theropods including the dromaeosaurid Itemirus, the tyrannosauroid Timurlengia, and the troodontid Urbacodon. The hadrosaur Levnesovia, ankylosaurs, and the sauropod Dzharatitanis represented the herbivores in this ecosystem.
