William Babcock Hazen (September 27, 1830 – January 16, 1887) was a career United States Army officer who served in the Indian Wars, as a Union general in the American Civil War, and as Chief Signal Officer of the U.S. Army. His most famous service was defending "Hell's Half Acre" at the Battle of Stones River in 1862.

Hazen was born in West Hartford, Vermont, but moved to Ohio at the age of three. He spent his boyhood in the town of Hiram and formed a close personal friendship with future President James A. Garfield. He graduated from the United States Military Academy, in 1855, and was commissioned a second lieutenant in the 4th U.S. Infantry. Before the Civil War, he served primarily in the Pacific Northwest and Texas, where he was wounded severely on November 3, 1859, during a fight with the Comanches along the Llano River. He was absent on sick leave until 1861.

Soon after the fall of Fort Sumter, he was promoted to captain of the 8th U.S. Infantry, and by October 29, 1861, he was Colonel of the 41st Ohio Infantry. Starting in January 1862, he commanded a brigade in the Army of the Ohio, under Maj. Gen. Don Carlos Buell. His first major battle was Shiloh, where Buell's army arrived on the second day (April 7, 1862), in time to counterattack the Confederate army for a Union victory.
