The William Jefferson Clinton Federal Building is a complex of several historic buildings located in the Federal Triangle in Washington, D.C., across 12th Street, NW from the Old Post Office. The complex now houses the headquarters of the Environmental Protection Agency (EPA).

One component of the complex was originally called the New Post Office, and housed the headquarters of the Post Office Department until that department was replaced by the United States Postal Service in 1971 and which vacated the building. Subsequently, the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE) occupied this building, which Congress renamed as the Ariel Rios Federal Building in 1985. BATFE vacated the building in the early 1990s, and EPA moved in after a renovation.

To consolidate its headquarters offices, EPA also took occupancy of two adjacent buildings beginning in the late 1990s: the Interstate Commerce Commission (ICC) building and the Department of Labor Building, on Constitution Avenue, NW. In 2013, Congress renamed the Ariel Rios Federal Building in honor of former President Bill Clinton, and the General Services Administration extended the designation to the former ICC and Labor buildings. (The new BATFE headquarters building received the name Ariel Rios Federal Building in 2016.^[2])
