亨利·诺克斯（英语：Henry Knox，1750年7月25日－1806年10月25日），美国独立战争时期大陆军将军，美国立国后担任美国战争部长。

诺克斯生于1750年波士顿，幼年就读波士顿拉丁学院，但因父亲早丧，而要到书店工作，期间养成对军事及火炮的兴趣。1770年波士顿大屠杀发生，诺克斯亦在现场，后来曾到法庭作供。1771年诺克斯另立门户，开设书店，并与弥敦内尔·格连结为至交。

1774年，诺克斯与一名女子结婚。诺克斯本身支持自由之子，并协助商人拒绝卸载英国茶叶；而他的亲家却是效忠派，一直反对亲事，并想诺克斯加入英国陆军。

Henry Knox (July 25, 1750 – October 25, 1806) was a military officer of the Continental Army and later the United States Army, who also served as the first United States Secretary of War from 1789 to 1794.

Born and raised in Boston, Massachusetts, he owned and operated a bookstore there, cultivating an interest in military history and joining a local artillery company. When the American Revolutionary War broke out in 1775, he befriended General George Washington, and quickly rose to become the chief artillery officer of the Continental Army. In this role he accompanied Washington on most of his campaigns, and had some involvement in many major actions of the war. He established training centers for artillerymen and manufacturing facilities for weaponry that were valuable assets to the fledgling nation.
