Troas (/ˈtroʊəs/; Ancient Greek: Τρῳάς, Trōiás or Τρωϊάς, Trōïás) is a historical region in northwestern Anatolia. It corresponds with the Biga Peninsula (Turkish: Biga Yarımadası) 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 Simoeis, which join at the area containing the ruins of Troy.
