The federal government of the United States (U.S. federal government or U.S. government) is the national government of the United States.

The United States federal government is composed of three distinct branches: legislative, executive, and judicial. The powers of these three branches are defined and vested by the Constitution of the United States, which has been in continuous effect since March 4, 1789. The powers and duties of these branches are further defined by acts of Congress, including the creation of executive departments and courts subordinate to the Supreme Court of the United States.

In the federal division of power, the federal government shares sovereignty with each of the 50 states in their respective territories. United States law recognizes Indigenous tribes as possessing sovereign powers, while being subject to federal jurisdiction.
