JOHN ELLIS WOOL (February 20, 1784 - November 10, 1869) was an officer in the United States Army during three consecutive U.S. wars: the War of 1812, the Mexican-American War and the American Civil War. By the time of the Mexican-American War , he was widely considered one of the most capable officers in the army and a superb organizer.

He was one of the four general officers of the United States Army in 1861, and was the one who had the most Civil War service. When the war began, Wool, age 77 and a brigadier general for 20 years, commanded the Department of the East. He was the oldest general on either side of the war.

John Ellis Wool was born in Newburg, New York. He read the law with an established firm in order to learn and be admitted to the bar. In the early days of the Civil War, Wool’s quick and decisive moves secured Fort Monroe, Virginia, for the Union. The fort guarded the entrance to Chesapeake Bay and the James River, overlooking Hampton Roads and the Gosport Navy Yard, which the Confederates had seized. It was to serve as the principal supply depot of Maj. Gen. George B. McClellan’s Peninsula Campaign.
