Yanbeilong (meaning "north of Yanmen Pass dragon") is an extinct genus of stegosaurian dinosaurs from the Early Cretaceous (Albian age) Zuoyun Formation of Shanxi, China. The genus contains a single species, Yanbeilong ultimus, known from a single partial skeleton including several vertebrae and the pelvic girdle. It is one of the youngest known stegosaurs, alongside Mongolostegus from Mongolia and unnamed stegosaurine remains from the Hekou Group of China, both of which date to the Aptian–Albian ages.
