Dover House is a Grade I-listed mansion in Whitehall, and the London headquarters of the Scotland Office.

Dover House was designed by James Paine as the London townhouse of Sir Matthew Fetherstonhaugh, Bart., MP, in the 1750s.

It has also been home to a French ambassador and Lady Caroline Lamb, with whom the Romantic poet Lord Byron famously had an affair.

The last private owners were the family of the Whig politician George James Welbore Agar-Ellis, created (1831) Baron Dover, whose title it has retained.

In 1946 the Glasgow Herald speculated that "It will not be many years before the building will be put to demolition and new Government offices raised on the site.
