Struthiomimus was a genus of ornithomimid dinosaur from the Late Cretaceous of Alberta (Canada). Fossils had been found in places such as Alberta (Canada), Coahuila (Mexico) and Saskatchewan (Canada). It comes from the Greek word στρούθειος/struthious meaning "of the ostrich" and μῖμος/mimos meaning "mimic" or "mimic" or, in short, "ostrich mimic". It was a long-legged, ostrich-like dinosaur.

Struthiomimus was a biped that was about 14 feet long and 4.6 feet tall at the hips and weighed about 330 pounds. It was a feathered dinosaur that belonged to a group known as Ornithomimidae. 

It had a skeletal structure typical of an ornithomimid, differing from closely related genera such as Ornithomimus and Gallimimimus in proportions and anatomical details. It had small, slender heads on long necks. It had large eyes and its jaws were toothless. The vertebral columns consisted of ten neck vertebrae, thirteen back vertebrae, six hip vertebrae and about thirty-five tail vertebrae. 

It had a stiff tail used for balance. It had long, thin arms and hands, with immobile forearm bones and limited opposability between the first finger and the other two.

Struthiomimus had a concave upper jaw and stout forelimbs. It had been an omnivore or herbivore that ate insects, crabs, shrimp and possibly eggs of other dinosaurs.
