The Troad or Troas is a historical region in northwestern Anatolia. It corresponds with the Biga Peninsula in the Çanakkale province of modern Turkey. Bounded by the Dardanelles to the northwest, by the Aegean Sea to the west and separated from the rest of Anatolia by the massif that forms Mount Ida, the Troad is drained by two main rivers, the Scamander (Karamenderes) and the Simois, which join at the area containing the ruins of Troy.
