The Elmisaurus is a small theropoda oviraptorosauria. The generic name Elmisaurus is derived from the Mongol 'elmyi' or 'olmyi', which means 'foot sole', as one of their specimens is a metatarsus. This species is from Mongolia. The specific name means 'rare' in Latin terms. These species are classified among the Dinosauria, Saurischia, Theropoda, and Caenagnathidae.

This North American therapod dinosaur is from the Late Cretaceous period of Campanian. The Elmisaurus females were oviparous theropods and reproduced young ones by laying eggs in clutches.

Halszka Osmólska described the theropod dinosaurs and distinguished them from the Chirostenotes pergracilis of North America. It was discovered through specimens from the Upper Campanian Aguja Formation that these crested dinosaurs had feathers on their front limbs.

Elmisaurus, which differed from the Chirostenotes pergracilis specimen, was an omnivore that ate small insects, invertebrates, small animals, and green plants. The second species, Elmisaurus elegans, was named in 1989 by Philip J. Currie.
