Dumbarton Oaks, formally the Dumbarton Oaks Research Library and Collection, is a historic estate in the Georgetown neighborhood of Washington, D.C. It was the residence and gardens of wealthy U.S. diplomat Robert Woods Bliss and his wife Mildred Barnes Bliss. The estate was founded by the Bliss couple, who gave the home and gardens to Harvard University in 1940. In 1944, it was the site of the Dumbarton Oaks Conference to plan for the post-WWII United Nations. The part of the landscaped portion of the estate that was designed as an enhanced "natural" area, was given to the National Park Service and is now Dumbarton Oaks Park.

Georgetown is a historic neighborhood and commercial district in Northwest Washington, D.C., situated along the Potomac River. Founded in 1751 as part of the colonial-era Province of Maryland, Georgetown predated the establishment of Washington, D.C. by 40 years. Georgetown was an independent municipality until 1871 when the United States Congress created a new consolidated government for the entire District of Columbia. A separate act, passed in 1895, repealed Georgetown's remaining local ordinances and renamed Georgetown's streets to conform with those in Washington, D.C..
