The action off Galveston Light was a short naval battle fought during the American Civil War in January 1863. Confederate raider CSS Alabama encountered and sank the United States Navy steamer USS Hatteras off Galveston Lighthouse in Texas.

CSS Alabama was a screw sloop-of-war built in 1862 for the Confederate States Navy at Birkenhead on the River Mersey opposite Liverpool, England by John Laird Sons and Company. Alabama served as a successful commerce raider, attacking Union merchant and naval ships over the course of her two-year career, during which she never docked at a Southern port. She was sunk in June 1864 by USS Kearsarge at the Battle of Cherbourg outside the port of Cherbourg, France.
