Major General Samuel McRoberts (December 20, 1868 – September 8, 1947) was an American attorney, businessman, and U.S. Army officer. He was notable for his success as a manager with the Armour corporation, and an executive and board of directors member for numerous other corporations and banks. During World War I, he was commissioned as a major and promoted to brigadier general as one of several business leaders who were recruited to government and military service in order to provide guidance and advice on the acquisition and production of war materiel. McRoberts continued to serve in the Organized Reserve even after retiring from business in 1925, and provided input to the War Department on the equipping of the Army until retiring as a major general in 1938.
