Bellulornis ("beautiful bird") is an extinct genus of ornithuromorph avialan. It is known from a complete postcranial skeleton lacking the skull which was unearthed from the rocks of the Early Cretaceous-aged Jiufotang Formation in Liaoning Province, China. It was originally given the genus name "Bellulia", meaning "beautiful", in reference to the fact that the skeleton was preserved in a pose reminiscent of a dancer. However, it was discovered after publication that the genus "Bellulia" was preoccupied by an extant moth. The authors then amended the name to "Bellulornis", adding the Ancient Greek suffix meaning "bird".
