The 29th Ohio Infantry Regiment was a volunteer infantry regiment in the Union Army during the American Civil War. Raised in the northeastern part of the state of Ohio, the 29th served with distinction in several battles of the Atlanta Campaign.

The regiment was organized from August 14, 1861, through March 13, 1862, at Jefferson, Ohio, by famed statesman Joshua Reed Giddings. Mustered into the army to serve three years, the regiment was composed primarily of recruits from Northeastern Ohio counties. Col. Louis P. Buckley served as the first regimental commander.

The 29th Ohio Infantry served for some time in the defenses of Winchester, Virginia, and participated in the battles of Port Republic, Cedar Mountain, Chancellorsville, Gettysburg, Davis' Cross Roads, New Hope Church, Dallas, Pine Knob, Peachtree Creek and during the Carolinas Campaign.^[1]

On the expiration of its three-year term of service, the surviving original members were mustered out, and the organization, composed of veterans and recruits, remained in service until July 13, 1865, when it was mustered out in Cleveland accordance with orders from the War Department.

The regiment had a total of 1,529 members during the war, of whom 540 were either killed, wounded or missing in action.
