The type species, Fulgurotherium australe, was named by Friedrich von Huene in 1932.[1] The genus name is derived from Latin fulgur, "lightning", and Greek therion, "beast", a reference to the Lightning Ridge site in New South Wales. The specific name means "southern" in Latin. The holotype is BMNH R.3719, the opalised lower end of a femur, indicating a total body length of 1 to 1.5 metres.

Von Huene thought it was a theropod, a member of the Ornithomimidae.[2] It has later been described as a hypsilophodont, a primitive ornithopod.[3] However, this was based on a contentious reference of bones found in the Dinosaur Cove, leading to a possible confusion between multiple species of Euornithopoda. Most researchers today consider it a nomen dubium.

Its name is an unusual example of a name in which -therium was used for an animal which is not an extinct mammal.
