Gairlochy (Scottish Gaelic: Geàrr Lòchaidh) is a clachan, or hamlet, of population approx.

Gairlochy is surrounded by several other small crofting settlements, the largest of which is Achnacarry.

Also close by is Highbridge, the site of the first skirmish of the 1745 Jacobite uprising.

Between 1803 and 1822, the Caledonian Canal was built, passing through Gairlochy, over the original site of the River Lochy.

Completed in 1896, the Invergarry and Fort Augustus Railway passed through the clachan, with a small island-platform station, called Gairlochy Station,[2] in nearby Mucomir, the current site of a caravan park and Mucomir hydro-electric power station.
