United States administrative law encompasses a number of statutes and cases which define the extent of the powers and responsibilities held by administrative agencies of the United States Government. The executive, legislative, and judicial branches of the U.S. federal government cannot always directly perform their constitutional responsibilities. Specialized powers are therefore delegated to an agency, board, or commission. These administrative governmental bodies oversee and monitor activities in complex areas, such as commercial aviation, medical device manufacturing, and securities markets.

L' United States administrative law (le « Droit administratif des États-Unis ») est composé de nombre de statuts et par la jurisprudence qui définit l'étendue des pouvoirs et responsabilités que détiennent les agences du gouvernement fédéral des États-Unis.
