The Charleston Harbor is an inlet (8 sq mi/20.7 km²) of the Atlantic Ocean at Charleston, South Carolina. The inlet is formed by the junction of Ashley and Cooper rivers at 32°49′7.10″N 79°55′40.41″W / 32.8186389°N 79.9278917°W / 32.8186389; -79.9278917. Morris and Sullivan's Islands shelter the entrance. Charleston Harbor is part of the Intracoastal Waterway.[1]

Like most river mouths in the Southeast, the inlet is evidence of a drowned coastline, created by a rise in sea level in recent geologic time.


Charleston Harbor was the site of the first successful submarine attack in history on February 17, 1864, when the H.L. Hunley made a daring night attack on the USS Housatonic, during the American Civil War.[2]
