Kompsornis (meaning "elegant bird") is an extinct genus of avialan dinosaurs that lived during the Early Cretaceous period of China. The type and only known species is Kompsornis longicaudus; the specific name means "long-tailed". It is known from only a single fossil specimen from the Jiufotang Formation. Kompsornis was closely related to the well-known Jeholornis, another long-tailed avialan from China, but differs from it in features of its skeleton, particularly the fusion and growth rate of its bones. Like other jeholornithiforms, Kompsornis was a long-tailed avialan with long wings and possessed little or no teeth, with none identified in the single specimen of Kompsornis.
