Cuspirostrisornis is a genus of enantiornithean bird. Only one species is known, Cuspirostrisornis houi, though some researchers believe this to be a synonym of the similar species Cathayornis yandica. It is known from one fossil found in the Jiufotang Formation in Liaoning province, People's Republic of China. The Jiufotang Formation is dated to the Early Cretaceous period, Aptian age, 120.3 +/-0.7 million years ago.

C. houi is known from a nearly complete fossil. The holotype fossil is in the collection of the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, China. The fossil is given catalog number IVPP V 10897. It was collected in 1993 by Dr. Hou Lianhai and Hou Jinfeng, the illustrator at IVPP. It was collected from light gray mudstones approximately two kilometers west of Boluochi Village, Chaoyang County, Liaoning Province.
