The Battle of Cherbourg, or sometimes the Battle off Cherbourg or the Sinking of CSS Alabama, was a single-ship action fought during the American Civil War between the United States Navy warship, USS Kearsarge, and the Confederate States Navy warship, CSS Alabama, on June 19, 1864, off Cherbourg, France.

USS Kearsarge, a Mohican-class sloop-of-war, is best known for her defeat of the Confederate commerce raider CSS Alabama off Cherbourg, France during the American Civil War. Kearsarge was the only ship of the United States Navy named for Mount Kearsarge in New Hampshire. Subsequent ships were later named Kearsarge in honor of the ship.
