GRENIKOS (or Granicus) was a River-God of the Troad in Northern Mysia, Anatolia (modern Turkey).
The River Grenikos had its headwaters in the foothills of Mount Ida, and emptied into the Hellespont near the Mysian town of Priapos. The major eighbouring rivers were Aisepos to the east, and Rhodios in the west.
GRANI′CUS (Granikos), a river god of Mysia, is described by Hesiod (Theog. 342) as a son of Oceanus and Thetys. But according to Stephanus Byzantinus (s. v. Graikos), the name Granicus was derived by some from Graecus, the son of Thessalus.

Homer, Iliad 12. 18 ff (trans. Lattimore) (Greek epic C8th B.C.) :
"[After the Greek had departed from Troy :] Poseidon and Apollon took counsel to wreck the wall [built by the Greeks], letting loose the strength of rivers upon it, all the rivers that run to the sea from the mountains of Ida, Rhesos and Heptaporos, Karesos and Rhodios, Grenikos and Aisepos, and immortal Skamandros and Simoeis . . . Phoibos Apollon turned the mouths of these waters together and nine days long threw the flood against the wall, and Zeus rained incessantly, to break the wall faster and wash it seaward. And the shaker of the earth himself holding in his hands the trident guided them, and hurled into the waves all the bastions' strengthening of logs and stones . . . and turned the rivers again to make their way down the same channel where before they had run the bright stream of their water."
