USS Antietam (CG-54) is a decommissioned Ticonderoga-class guided missile cruiser of the United States Navy. Antietam was named for the site of the 1862 Battle of Antietam, Maryland, between Confederate forces under General Robert E. Lee and Union forces under Major General George McClellan, during the American Civil War. Antietam earned the 2007 and 2008 Battle Efficiency awards, also known as the "Navy E" or "Battle E" award, for the John C. Stennis Strike Group.
