Frogmore Cottage is an historic Grade II listed house in the grounds of Frogmore House built in 1801 at the direction of Queen Charlotte on the Frogmore Estate, part of Home Park, Windsor, Berkshire, England. According to preservationists, the cottage warrants every effort to preserve it for its historic value. A part of the Crown Estate, it is currently the home of the Duke and Duchess of Sussex, and their son, Archie Mountbatten-Windsor.
The cottage was originally known as Double Garden Cottage and was listed in Queen Charlotte's 1801 accounts for her garden as having been built for £450 by a Mr. Bowen. Queen Victoria had breakfast at the cottage on 28 June 1875 and noted an "immense number of little frogs" which she found "quite disgusting". The cottage has been listed Grade II on the National Heritage List for England since October 1975. The listing provides little of the history: "Early C19 plain 2 storey house with parapet. Centre break with porch. Glazing bar sashes. Stucco faced." 
The cottage was a retreat for Queen Charlotte and her unmarried daughters. The theologian Henry James Sr. and his family lived at the cottage in the 1840s. A personal secretary of Queen Victoria's, Abdul Karim, moved to Frogmore Cottage in 1897 with his wife and father. Grand Duchess Xenia Alexandrovna of Russia in exile from her native Russia stayed there in the 1920s.
In the early 21st century the cottage was a series of five separate units housing Windsor estate workers.
In 2019, the house was converted to serve again as a 4-bedroom & nursery, single-family home, at a reported cost from the Sovereign Grant of £2.4 million "of taxpayer-funded costs, royal accounts show", according to a BBC report. There was some criticism at this use of public money, however, as a property of a royal palace of state and designated heritage site, Frogmore Cottage was always scheduled to be renovated, regardless of occupant. The Duke and Duchess of Sussex, who had earlier held their wedding reception at nearby Frogmore House, moved from Nottingham Cottage to Frogmore Cottage in spring 2019, before the birth of their first child, Archie Mountbatten-Windsor.
