Michael Calum Campbell, Marquess of Lorne (born 12 July 1999), is the heir apparent to the Dukedom of Argyll.

Campbell was born as the first and only son of Ian Campbell, 12th Duke of Argyll and Ava Campbell, Duchess of Argyll. He became heir apparent to the dukedom at birth since his father was already the Duke when he was born.

He's currently studying in London at Eton College, like his father and many ancestors did before him and is aspiring to study Geography at the University of St. Andrews.
