USS Boxer (CV/CVA/CVS-21, LPH-4) was one of 24 Essex-class aircraft carriers of the United States (U.S.) Navy, and the fifth ship to be named for the HMS Boxer. She was launched on 14 December 1944 and christened by the daughter of a US Senator from Louisiana. Although she was extensively modified internally as part of her conversion to an LPH, external modifications were minor, so throughout her career Boxer retained the classic appearance of a World War II Essex-class ship. She was decommissioned on 1 December 1969 after 25 years of service and sold for scrap.
