Chromeornis (; ) is an extinct genus of longipterygid enantiornithean bird known from the Early Cretaceous (Aptian age) Jiufotang Formation of China. The genus contains a single species, Chromeornis funkyi, known from most of an articulated skeleton preserved on a slab and counterslab. This specimen was found with a mass of gastroliths in the esophagus, but these were likely not the gizzard stones expected in the gizzard of some birds. Instead, they may have been the result of an illness, with the animal dying after attempting to regurgitate them.

== Discovery and naming == The Chromeornis fossil material was discovered in outcrops of the Jiufotang Formation near Lamadong Town of Liaoning Province, China. The specimen is housed in the Shandong Tianyu Museum of Nature in Shandong Province, China, where it is permanently accessioned as specimen STM7-156. The specimen consists of most of an articulated skeleton with associated feathers, belonging to a single individual preserved on a slab and counterslab. Most of the pelvis and the left pedal (foot) digits are not preserved, and the right forelimb and remaining pelvic material are disarticulated.
