The 23rd Ohio Infantry Regiment was an infantry regiment in the Union Army during much of the American Civil War. It served in the Eastern Theater in a variety of campaigns and battles, and is remembered with a stone memorial on the Antietam National Battlefield not far from Burnside's Bridge.

The regiment later became noted for its many up-and-coming politicians. Future presidents Rutherford B. Hayes and William McKinley served in this unit, as did future U.S. senator and associate justice of the United States Supreme Court Stanley Matthews and Robert P. Kennedy, a future U.S. Congressman. Other notable officers included James M. Comly and Eliakim P. Scammon, both of whom became influential nationally after the war. Harrison Gray Otis, the famed owner and publisher of the Los Angeles Times, also fought with the 23rd Ohio during the war.
