The Supreme Court Building houses the Supreme Court of the United States, the highest court in the federal judiciary of the United States. The building serves as the official workplace of the chief justice of the United States and the eight associate justices of the Supreme Court. It is located at 1 First Street in Northeast Washington, D.C. It is one block immediately east of the United States Capitol and north of the Library of Congress. The building is managed by the Architect of the Capitol. On May 4, 1987, the Supreme Court Building was designated a National Historic Landmark.

The Supreme Court of the United States (SCOTUS) is the highest court in the federal judiciary of the United States. It has ultimate appellate jurisdiction over all U.S. federal court cases, and over state court cases that turn on questions of U.S. constitutional or federal law. It also has original jurisdiction over a narrow range of cases, specifically "all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party." The court holds the power of judicial review: the ability to invalidate a statute for violating a provision of the Constitution. It is also able to strike down presidential directives for violating either the Constitution or statutory law.
