Viscount of Arbuthnott is a title in the Peerage of Scotland. It was created in 1641, along with the subsidiary title Lord Inverbervie, for Sir Robert Arbuthnott. The Viscount of Arbuthnott is the hereditary chief of Clan Arbuthnott. At the time of the 16th Viscount's death in 2012, the family held the genealogical record of being one of an unbroken male line living in the same spot for more than 800 years. Around 1188, William the Lion granted ancestor Hugh de Swinton the lands of Arbuthnott, where the family estate and clan association headquarters remains to this day.
