Orpheus Graves is a small cemetery on Cornwallis Road in Cornwallis, on the Manukau Harbour in West Auckland. It marks the graves of three unknown sailors who died when HMS Orpheus was wrecked at the entrance to the Manukau Harbour on 7 February.
For a visitor, the site is a quiet place to stop and remember the sailors who lost their lives at the harbour mouth. The graves sit on the road side of the harbour, and the wreck is part of the story of the harbour's dangerous entrance for ships.
