Hoy Sound is a body of salt water subject to tidal currents situated south of the town of Stromness in the Orkney archipelago of Scotland.
The sound lies north of the island of Hoy and to the south of Mainland Orkney.
To the west are the open waters of the Atlantic Ocean and the natural harbour of Scapa Flow is to the east.
[1] The Bay of Ireland north of Hoy Sound communicates with Loch of Stenness and Loch of Harray.
