A mansion house in Strathearn, Perth and Kinross, Dupplin Castle lies 5 miles (8 km) southwest of Perth. Built in 1828-32, it replaced an earlier castle destroyed by fire, the seat of the Hay Earls of Kinnoull. The mansion later became the home of Perth whisky baron John Dewar, Lord Forteviot (1856 - 1929).
Nearby stood a stone cross marking the site of a battle that took place in August 1332 at which Edward Balliol defeated the Earl of Mar. The Dupplin Cross is now located in St. Serf's Church in Dunning.
