Ardfin is a country estate on the island of Jura, Inner Hebrides, Scotland. It is situated at the southern tip of the island, between Feolin and Craighouse. It includes Jura House which is a Category C listed building. The old house was extended by architect William Burn in 1838 for the laird Colin Campbell, with further extensions in 1878 by Alexander Ross and circa 1900 by Ronald Carswell. The next owners from 1938 were the Riley-Smith family, owners of John Smith's Brewery in Tadcaster, North Yorkshire. The estate was sold in 2010 after the death of Tony Riley-Smith. The gardens are home to specimen plants from Australasia, which were held in high regard by horticulturalists. The estate also includes 16 kilometres (10 mi) of coastline and seven islands over a total of 4,692.3 hectares.
