The Old Patent Office Building is a historic building in Washington, D.C. that covers an entire city block between F and G Streets and 7th and 9th Streets NW in the Penn Quarter section of Chinatown. Built 1836–1867 in the Greek Revival style, the building first served as one of the earliest U.S. Patent Office buildings.
The building has housed many U.S. federal government departments, including the first exhibits of the Smithsonian Institution. The structure now houses two Smithsonian art museums: the Smithsonian American Art Museum and the National Portrait Gallery.
