A sea loch on the coast of Wester Ross, Highland Council Area, Loch Ewe is 10 miles (16 km) in length and lies between two peninsulas with the settlement of Poolewe at its head. The Isle of Ewe lies opposite Aultbea and Inverewe Gardens created by Osgood Mackenzie lie on an inlet to the east of Poolewe. Loch Ewe receives the River Ewe which flows northwestwards for just over 3 miles (5 km) from Loch Maree.
During World War II, convoys assembled here before setting sail for Arctic Russia and the loch was heavily defended with artillery, anti-aircraft guns, mines and anti-submarine nets.
