The Dupont Circle Building is a landmark art deco building on the south end of Dupont Circle in Washington DC.

[1] By October 1944, it had become the head office of the United Nations Relief and Rehabilitation Administration,[2] which would remain there until its end in the late 1940s.

[3] At that time the main entrance was numbered 1344 Connecticut Avenue NW, which was later changed to 1350.

The American Institute of Architects's guide to the architecture of Washington DC assesses the Dupont Circle Building's bas-relief ornament as "genius" and judges that in respect of the interplay between ornament and geometry, "it outdoes New York's famous Flatiron Building.

"[4] By 2023, the tip of the building facing Dupont Circle was the location of a Krispy Kreme store, and one of the building's main tenants was the Gault Center.
