Ornatops (meaning "ornate face") is a genus of brachylophosaurin saurolophine hadrosaur from the Late Cretaceous Menefee Formation of New Mexico, United States.

The fossil material was discovered by staff and volunteers from the Western Science Center, Zuni Dinosaur Institute for Geosciences, and Southwest Paleontological Society.

The holotype consists of a well-preserved skull lacking the maxillae and lower jaws, two dorsal vertebrae, a rib, ossified tendons, the right scapula, most of the right humerus, ulna, and radius, the second and third right metacarpals as well as an incomplete ilium and ischium, making it the most complete dinosaur from the Menefee Formation.

Its generic name, Ornatops, means "ornate face" from Latin ornatus and Greek ops, in reference to the elaborate nasofrontal suture.

Ornatops incantatus was a genus of brachylophosaurin hadrosaurid that existed in what is now New Mexico, United States approximately 78 million years ago.
