Othnielia is a genus of ornithischian dinosaur, named after its original describer, Professor Othniel Charles Marsh, an American paleontologist of the 19th century.

He considered the femur undiagnostic and thus Othnielia to be a dubious name, and removed two partial skeletons to the new genus Othnielosaurus.
