Clan Mackay (Gaelic: Mac Aoidh) is an ancient and once-powerful clan from the far north of the Scottish Highlands.

Formed in 1808 as the 'Mackays' Society', we are one of the oldest clan societies in Scotland. The original organisation operated for some 50 years and after a period of abeyance was reconstituted in 1888 as The Clan Mackay Society.

The Clan Mackay Society seeks to preserve the Mackay heritage for future generations; create a community to bring together those with the Mackay name; and cultivate a sense of pride in belonging to the Clan Mackay.

The Society is currently administered by a council with a membership made up from 11 countries around the world.
