In Greek mythology, Poena or Poine () is the spirit of punishment and the attendant of punishment to Nemesis, the goddess of divine retribution. Some depictions are of a single being, and some depictions are of multiple beings—in the plural, the name is Poenai (); the Poenai are akin to the Erinyes.A Dictionary of Greek and Roman biography and mythology, Poena
The Greek word () means "a recompense or a punishment". From this word is derived the Latin word poena meaning "pain, punishment, penalty", which in turn gave rise to English words such as subpoena and pain.
