Heshang Moheyan (和尚摩訶衍; Wade-Giles:Ho-shang Mo-ho-yen; Héshang Móhēyǎn or Hvashang Moheyan in Tibetan sources) was a late eighth century CE Chan monk associated with the Northern School and famous for representing Chan vs. Indian Buddhism in a debate that is supposed to have set the course of Tibetan Buddhism. Hva-shang is a Tibetan approximation of the Chinese hoshang, meaning monk. Hoshang in turn comes from the Sanskrit title upadhyaya.
