The SS Constitution was an ocean liner owned by American Export Lines, sister ship of the SS Independence. Both were constructed in the United States and made their maiden voyages in 1951.

SS Independence was an American built passenger liner, which entered service in February 1951 for American Export Lines. Originally, she plied a New York-Mediterranean route, specializing in a high-end clientele, sailing one way while her sister ship, SS Constitution, plied the route the opposite. Starting in 1980 she sailed as a cruise ship. She was shortly joined by her similarly graceful counter sterned sibling, the pair sharing the Hawaiian islands together for the better part of two decades until their retirements.
