Dalmeny House is a Gothic revival mansion located in an estate close to Dalmeny on the Firth of Forth, in the north-west of Edinburgh, Scotland. It was designed by William Wilkins, and completed in 1817. Dalmeny House is the home of the Earl and Countess of Rosebery. The house was the first in Scotland to be built in the Tudor Revival style. It provided more comfortable accommodation than the former ancestral residence, Barnbougle Castle, which still stands close by. Dalmeny today remains a private house, although it is open to the public during the summer months. The house is protected as a category A listed building, while the grounds are included in the Inventory of Gardens and Designed Landscapes in Scotland.
