In Greek mythology, Stentor (Greek: Στέντωρ; gen.: Στέντορος) was a herald of the Greek forces during the Trojan War. Although he is mentioned only briefly in Homer's Iliad, in which Hera takes Stentor's character to encourage the Greeks to fight, his name has been living in the term "stentorian" voice, meaning loud-voiced, for which he was famous: Homer said his "voice was as powerful as fifty voices of other men". Elsewhere, he is said to have died after his defeat by Hermes in a shouting contest. Aristotle uses the concept of a Stentor in his Politics Book 7, Chapter IV saying, "For who can be the general of such a vast multitude, or who the herald, unless he have the voice of a Stentor?"
