The Douglas House was a US servicemen's club operated by the United States Air Force for twenty-five years at two different locations in London's West End.

The club's purpose was to provide "home-style service" for the thousands of American airmen based in the United Kingdom and US servicemen of all branches who might be passing through.

[3] The second Douglas House, on Lancaster Gate, had 110 low-cost hotel rooms for families as well as singles, a restaurant, nightclub, soda bar, four-chair barber shop, TV lounge, bureau de change, and a newsstand that sold American periodicals.

The building that housed the second club was originally a block of white stuccoed flats or townhouses built in the Victorian era as part of a Bayswater area real estate development.

A blue plaque, attached to the Leinster Terrace end of the building in 1977, commemorates American author Bret Harte, who resided and died at 74 Lancaster Gate in 1902.
