Vorona (/ˈvʊəruːnə/ VOOR-oo-nə; Malagasy for "bird", V. berivotrensis, "from Berivotra") is a monotypic genus of prehistoric birds. It was described from fossils found in a Maevarano Formation quarry near the village of Berivotra, Mahajanga Province, Madagascar. The age is Late Cretaceous, probably Campanian (70.6–83.5 mya). V. berivotrensis is known from scattered remains, possibly from a single individual (UA 8651 and FMNH PA715).
The phylogenic affiliation of Vorona is hard to determine due to the fragmentary nature of the remains, mainly because the fossil shows a mix of primitive avian features as well as some that seem very modern. Vorona might be a primitive ornithuromorph.
Vorona is sometimes confused with the dromaeosaur Rahonavis ostromi, a fossil of which was found in the same location. This confusion has led to the common misconception that Vorona had a deinonychosaur-like sickle claw on each foot.
