The Tyrrhenians (Attic Greek: Τυρρηνοί Turrhēnoi) or Tyrsenians (Ionic: Τυρσηνοί Tursēnoi; Doric: Τυρσανοί Tursānoi) is an exonym used by Greek authors to refer to a non-Greek people.
While ancient sources have been interpreted in a variety of ways, one theory identifies the Tyrsenians with the Etruscan, Raeti, and Lemnian cultures, whose languages have been grouped together as the Tyrsenian languages based on strong similarities in their written languages.
The origin of the name is uncertain. It is only known to be used by Greek authors, but apparently not of Greek origin. It has been connected to tursis, also a "Mediterranean" loan into Greek, meaning "tower" (see there). Direct connections with Tusci, the Latin exonym for the Etruscans, from Turs-ci have also been attempted. See also Turan, tyrant.

Later, in the 6th to 5th centuries BC, the name referred specifically to the Etruscans, for whom the Tyrrhenian Sea is named, according to Strabo. In Pindar, the Tyrsanoi appear grouped with the Carthaginians as a threat to Magna Graecia:
