The Taurus Mountains (Turkish: Toros Dağları or Toroslar) are a mountain complex in southern Turkey, separating the Mediterranean coastal region from the central Anatolian Plateau. The system extends along a curve from Lake Eğirdir in the west to the upper reaches of the Euphrates and Tigris rivers in the east. It is a part of the Alpide belt in Eurasia. The mountain range under the current name was mentioned in The Histories by Polybius as Ταῦρος (Taûros). Heinrich Kiepert writes in Lehrbuch der alten Geographie that the name was borrowed into Ancient Greek from the Semitic (Old Aramaic) root טורא ṭūrā, meaning "mountain".
