Mirarce (meaning "wonderful winged messenger") is a genus of enantornithe bird from the Late Cretaceous of Utah. It contains a single species, M. eatoni. It was similar in size to modern turkeys.

== Discovery == thumb|left|Life reconstruction In 1992, in Utah, USA, paleontologist Howard Hutchison discovered fossilized remains of an enantiornithine bird. For a long time they have not been described; they were sometimes figured under the unofficial name of "Kaiparowits enantiornithine". The holotype, UCMP 139500, is well preserved in three dimensions. It consists of a partial postcranial skeleton without a skull, including 3 cervical and 2 thoracic vertebrae, a pygostyle, a furcula, the xiphoid process of the sternum, a fragment of the left scapula and a coracoid, the humerus, ulna, and radius with fragments of the manus, several fused fragments of the pelvic girdle, and some elements of the hind limbs. It is the most complete enantiornithine found in North America.
