Othnielia (pronounced: oth-Neel-ee-uh) is a genus of hypsilophodont dinosaur, named after its original describer, Professor Othniel Charles Marsh, an American paleontologist of the 19th century. The taxon, Othnielia rex, was named by Peter Galton in 1977 from a species Marsh (1877) called Nanosaurus rex.

Remains assigned to Othnielia have been found in Wyoming, Utah, and Colorado in rocks of the Late Jurassic age (Oxfordian-Tithonian) Morrison Formation, but with Galton’s 2006 revision of Morrison ornithischians, the only definite remains are YPM 1875 (the holotype femur of “Nanosaurus” ‘rex’) and possibly some other associated postcranial bits. He considered the femur undiagnostic and thus Othnielia to be a dubious name, and removed two partial skeletons to the new genus Othnielosaurus. It remains to be seen if this will be widely accepted, but this sort of taxonomic decision has much precedent (for example, Marasuchus versus Lagosuchus).
