The Department of War was a cabinet-level department of the United States government established on August 7, 1789, by President George Washington and the First Congress, making it one of the three original executive departments alongside State and Treasury. It was headed by a civilian Secretary of War (first held by General Henry Knox) and was responsible for operating, recruiting, training, and maintaining the U.S. Army for 158 years. Following the National Security Act of 1947, signed by President Harry S. Truman on July 26, 1947, the War Department was reorganized into the Department of the Army and consolidated with the Navy and the newly established Air Force under the National Military Establishment (renamed Department of Defense in 1949), ending the department's independent existence. The War Department's records, including those relevant to post-WWII military operations and early Cold War activities, have been preserved in the federal archives.

O Departamento de Guerra (Department of War) foi um departamento de nível gabinete do governo dos Estados Unidos, estabelecido em 7 de agosto de 1789, pelo presidente George Washington e pelo Primeiro Congresso, tornando-se um dos três departamentos executivos originais ao lado de Estado e Tesouro. Era chefiado por um Secretário da Guerra civis (ocupado primeiro pelo General Henry Knox) e era responsável por operar, recrutar, treinar e manter o Exército dos EUA por 158 anos. Após a Lei de Segurança Nacional de 1947, assinada pelo presidente Harry S. Truman em 26 de julho de 1947, o Departamento de Guerra foi reorganizado no Departamento do Exército e consolidado com a Marinha e a recém-estabelecida Força Aérea sob o Estabelecimento Militar Nacional (renomeado Departamento de Defesa em 1949), encerrando a existência independente do departamento. Os registros do Departamento de Guerra, incluindo aqueles relevantes para operações militares pós-Segunda Guerra Mundial e atividades do início da Guerra Fria, foram preservados nos arquivos federais.
