USS Lake Champlain (CV/CVA/CVS-39) was one of 24 Essex-class aircraft carriers completed during or shortly after World War II for the United States Navy. She was the second US Navy ship to bear the name, and was named for the Battle of Lake Champlain in the War of 1812. Lake Champlain was decommissioned in 1966 and sold for scrap in 1972.
