Antietam /ænˈtiːtəm/ may refer to:
The Battle of Antietam, or Battle of Sharpsburg particularly in the Southern United States, was a battle of the American Civil War fought on September 17, 1862, between Confederate Gen. Robert E. Lee's Army of Northern Virginia and Union Gen. George B. McClellan's Army of the Potomac near Sharpsburg, Maryland and Antietam Creek. Part of the Maryland Campaign, it was the first field army–level engagement in the Eastern Theater of the American Civil War to take place on Union soil. It remains the bloodiest day in American history, with a combined tally of 22,727 dead, wounded, or missing. Although the Union army suffered heavier casualties than the Confederates, the battle was a major turning point in the Union's favor.

The Battle of South Mountain—known in several early Southern accounts as the Battle of Boonsboro Gap—was fought on September 14, 1862, as part of the Maryland campaign of the American Civil War. Three pitched battles were fought for possession of three South Mountain passes: Crampton's, Turner's, and Fox's Gaps. Maj. Gen. George B. McClellan, commanding the Union Army of the Potomac, needed to pass through these gaps in his pursuit of Confederate General Robert E. Lee's precariously divided Army of Northern Virginia. Although the delay bought at South Mountain would allow him to reunite his army and forestall defeat in detail, Lee considered termination of the Maryland Campaign at nightfall.
The Battle of Harpers Ferry was fought September 12–15, 1862, as part of the Maryland Campaign of the American Civil War. As Confederate Army General Robert E.

The battlefield straddles the Monocacy River southeast of the city of Frederick, Maryland.

The Maryland campaign occurred September 4–20, 1862, during the American Civil War. Confederate Gen. Robert E. Lee's first invasion of the North was repulsed by the Army of the Potomac under Maj. Gen. George B. McClellan, who moved to intercept Lee and his Army of Northern Virginia and eventually attacked it near Sharpsburg, Maryland. The resulting Battle of Antietam was the bloodiest single-day battle in American history.
