Baron Rowallan, of Rowallan in the County of Ayr, is a title in the Peerage of the United Kingdom.^[1] It was created in 1911 for the Liberal politician Archibald Corbett. He had previously represented Glasgow Tradeston in the House of Commons. His son, the second Baron, fought in both World Wars, was Chief Scout and served as Governor of Tasmania. As of 2022^[update] the title is held by the latter's grandson, the fourth Baron, who succeeded his father in 1993.

The family seat was initially Rowallan Castle, near Kilmarnock, East Ayrshire. This historic property was bequeathed by the second Baron to his grandson, the future fourth Baron, bypassing the latter's father, the third Baron, possibly because the third baron had earned disrepute in a highly unusual divorce suit against his second wife, April Ashley. However, the fourth Baron was unable to retain ownership of the Castle; he inherited the property in 1977 but sold it in 1989 in order to pay his debts. The fourth Baron now resides at Meikle Mosside Farm, near Fenwick, Ayrshire, which may now be regarded as the family seat.
