Adrasteia or Adrastea (Ancient Greek: Ἀδράστεια, Homeric Ἀδρήστεια) was the name of a region, city, and valley of the ancient Troad or of Mysia, which was watered by the Granicus River. In the eponymous city was an oracle of Apollo and Artemis. The temple had been destroyed by the time of Strabo, and the stones used to build a large altar. Parium was a port of the region.
