Kilmory Castle, also known as Kilmory House, is a large 19th-century Gothic mansion located just south of Lochgilphead on Scotland's west coast. Designed by architect Joseph Gordon Davis, the house may have had medieval origins dating to the 14th century and remained in the Campbell family for over 250 years before later becoming the headquarters of Argyll and Bute Council. The property is protected as a category B listed building, and its gardens are open to the public as part of a country park.
