Orca Bay is on the north west and west sides of Hawkins Island, extending westward to Johnstone Point of Hinchenbrook Island.
Its northwestern corner is demarcated by Knowles Head, between Port Gravina and Fidalgo Bay on the mainland.
[1] Its eastern end can be reached from the port of Cordova, Alaska on Orca Inlet.
Ultimately the name is derived from the orca or killer whale.
It was renamed by the early twentieth century, to avoid confusion with Cordova Bay in Dixon Entrance, at the eastern extreme of the Gulf of Alaska.
