Noumenios () was a Seleucid general and satrap of the Province of Mesene (Characene, capital Antiochia in Susiana), who is said to have defeated the Persians sometime in the 3rd or 2nd century BCE. Pliny describes his ruler as being "Antiochos", but it is unknown if this is referring to Antiochos I, Antiochos II or Antiochos III, although the battle necessarily took place before 190-189 BCE, date of the Battle of Magnesia where Antiochos III was vanquished by the Romans. Alternatively, these events may have taken place during the reign of Antiochos IV.
