Dupplin Castle is a country house and former castle in Perth and Kinross, Scotland, situated to the west of Aberdalgie and northeast of Forteviot and Dunning. It overlooks Strath Earn. The earliest known owner of the castle was Sir William Oliphant in the late 13th century. The Battle of Dupplin Moor took place in the vicinity in 1332, when it was won by Edward Baliol. A fire gutted the castle in 1827, prompting a full rebuilding and restoration. In May 1617 Lord Oliphant stabbed his kinsman and heir Patrick Oliphant who was standing in the hall by the fire.
