Loch Cluanie (Scottish Gaelic: Loch Cluanaidh) is a loch in the Northwest Highlands of Scotland at the south-east end of Glen Shiel. It is a reservoir, contained behind the Cluanie Dam, constructed by Mitchell Construction and completed in 1957 as part of the North of Scotland Hydro-Electric Board's Glenmoriston project to generate hydroelectricity. Water feeds the dam from the west via two flows, from a tunnel from the dammed Loch Loyne and via the River Moriston. The A87 road runs along the north edge of the loch.
