Drumtochty Castle is a neo-gothic style castellated mansion erected in 1812 approximately three kilometres north-west of Auchenblae, Kincardineshire, Scotland. This building stands on the southern edge of Drumtochty Forest.

It was built to the designs of James Gillespie Graham with further extensions c. 1815. Although the design for the extensions was again commissioned from Gillespie Graham, the work was undertaken by the Aberdeen City Architect John Smith. Miller speculates Gillespie Graham could have had a dispute with George Drummond, the owner, but considers Smith’s closer proximity to the site is a more plausible scenario. Gillespie Graham was involved with further additions c. 1839.

During the Second World War, Drumtochty Castle was bought by the Norwegian government-in-exile and used as a boarding school for Norwegian children who were refugees from the German occupation of Norway.

On 1 May 1947, Robert and Elizabeth Langlands opened a boys’ preparatory school at the Castle, having bought Drumtochty from the Norwegian government. The school closed in 1971.

Historic Scotland included the castle on the list of category A listed buildings in August 1972.
