The generic name, Enigmacursor, comes from the word enigma, referring to the taxonomic confusion of Morrison Formation neornithischians such as Nanosaurus, and the Latin word cursor, meaning "runner", after its cursorial hindlimbs. The specific name, mollyborthwickae, honors Molly Borthwick, who donated the funds for the acquisition of the specimen by the NHM.
