Erectopus superbus (meaning erect foot) is an extinct genus of allosauroid theropod dinosaur that lived in France during the Early Cretaceous period. The original specimens were destroyed in World War II, but casts remain for study.

The etymology of Erectopus is based on the structure of the foot (Latin erectus = "upright" + Greek pous = "foot"). The specific name superbus means "proud" in Latin.


The material comprising the type series was discovered in the late 19th century from the Phosphate-bearing beds of La Penthiève (Mammilatum; lower Albian) at Louppy-le-Château in eastern France, which have also produced remains of plesiosaurs, ichthyosaurs, crocodiles.


Allain (2005 pp. 75-76) diagnoses Erectopus superbus as follows: "Rounded anterior ramus of maxilla; slender neck of femur; posterior curvature of proximal half of femur; anterodorsal edge of calcaneum dorsally projected; calcaneum twice as long as deep vertically; posteromedial process for tibia on articular surface of astragalus; length of second metatarsal equal to half the length of femur; lateral margin of proximal end of second metatarsal regularly concave."
