Dromiceiomimus is a genus of ornithomimid theropod from the Late Cretaceous (early Maastrichtian) of Alberta, Canada.

Dromiceiomimus was distinguished from Ornithomimus edmontonicus on the basis of the following characters: humerus shorter than scapula; ulna ~70% of femoral length; preacetabular process, tibia, metatarsus and pedal digit III longer compared to femur.

[3] In a 1981 publication, however, Nicholls and Russell cast doubt on the validity of Dromiceiomimus and though keeping it distinct from Ornithomimus argued that the limb proportions might be insufficient to distinguish ornithomimid taxa from each other.

[6][7][8][9] In 2018, Ian McDonald and Philip John Currie rejected the conclusions by Makovicky and colleagues.

They showed that the thighbone/shinbone ratio of specimen UALVP 16182, found in 1967 by Richard Fox and referred to Dromiceiomimus, differed significantly from that of Ornithomimus edmontonicus.
