Songlingornis is an extinct genus of ornithuromorph dinosaurs from the Early Cretaceous. Its fossils have been found in the Jiufotang Formation of Liaoning (PRC).[1] The age of these rocks is somewhat disputed, but probably around the early Aptian, 125-120 million years ago. Only one species, Songlingornis linghensis, is known at present.

It was a close relative of Yanornis and together with this and Yixianornis may form a clade.[2] It is sometimes considered to be the same genus as Yanornis (which, described after Songlingornis, would then be merged into that taxon),[3] but this is not universally accepted.[4]
