Liaoningornis (meaning "bird of Liaoning" in Greek) is a genus of bird from Lower Cretaceous China. It was collected from the dinosaur-bearing beds of the Sihetun locality, of the Yixian Formation, Shangyuan, near the city of Beipiao in Liaoning province. The only known species is Liaoningornis longidigitris. It was described by Linhai Hou in 1996 and 1997. Zhou and Hou in 2002 considered Liaoningornis to be the oldest known member of the Ornithurae. However, a 2012 re-analysis by Jingmai O'Connor showed that it was in fact an enantiornithine similar to Eoalulavis.
