Nashdom Abbey, also known as Nashdom Monastery, was formerly a country house and Anglican Benedictine abbey in Burnham, Buckinghamshire, England. This building, designed by architect Edwin Lutyens in the Neo-Georgian style, is a Grade II listed building. In 1997, it was converted into apartments. The abbey's gardens also hold Grade II status in the National Register of Historic Parks and Gardens. The name "Nashdom" comes from the Latinized Russian expression "Our Home." Lutyens' clients were Prince and Princess Dolgoruky.

Prince Alexei, son of Prince Sergei Dolgoruky, previously served as a chamberlain at the Russian court. In 1898, he married Frances, the only daughter and heiress of Scottish shipping magnate Fleetwood Pelham Wilson of Wappenham Hall in Northamptonshire. Their British residences included Braemar Castle in Aberdeenshire and a house on Upper Grosvenor Street in London.

The princess desired an additional residence for entertaining guests and hosting house parties. Lutyens visited the site in July 1905, noting its beauty but the difficulty of constructing the perfect house, which he estimated would cost £20,000. The original budget was £6,000, but they ultimately agreed on a project costing £15,000. Completion dates for the house vary in sources from 1908 to 1911.

The prince passed away at the age of 68 in June 1915. After his death, the princess lived in the Atlantic Pyrenees in France, where she died in August 1919 at the age of 69.

In her will, she left Nashdom for the use of the Dolgoruky family under the management of Sergei Alexandrovich Dolgoruky, with the support of executor Herbert Brisbane Yuart.
