Elopteryx is a genus of paravian theropod dinosaur based on fragmentary fossils found in Late Cretaceous rocks of Romania. The single species, Elopteryx nopcsai, was known only from very incomplete material until new specimens were reported in the 21st century. Balaur bondoc might represent a junior synonym of this taxon.
