Invergarry Castle in the Scottish Highlands was the seat of the Chiefs of the Clan MacDonell of Glengarry, a powerful branch of the Clan Donald. The castle's position overlooking Loch Oich on Creagan an Fhithich – the Raven's Rock – in the Great Glen, was a strategic one in the days of clan warfare. It is not certain when the first structure was erected on Creagan an Fhithich but there are at least two sites prior to the present castle.
