The U.S. General Services Administration Building is a historic office building and the headquarters of General Services Administration (GSA) located at 1800 F Street Northwest in Washington, D.C. Designed by Charles Butler in the neoclassical style, it was built between 1915 and 1917 and originally housed offices of the United States Department of the Interior. The building has a facade of Indiana limestone, with an E-shaped plan allowing for open courtyards, and a carved stone eagle and limestone panels designed by Ernest C. Bairstow. An oak-paneled Administrator's Suite is inside.

In 1935, the building underwent alterations with the construction of a seventh floor and the installation of air-conditioning. The Department of the Interior departed between 1937 and 1939, and the Federal Works Administration became the primary tenant. The GSA was established in 1949, absorbing the activities and offices of the Federal Works Administration. The building was listed in the National Register of Historic Places in 1976, and a renovation took place between 1999 and 2002.
