Four ships of the United States Navy have borne the name USS New Orleans
, after the city of New Orleans, Louisiana. One other ship that was never completed would have borne the name.
- What would have been the first New Orleans was never launched. During the War of 1812 there was a ship building race on Lake Ontario (at that time isolated from the sea), and Henry Eckford laid down a 130-gun ship of the line. The Battle of Sackett's Harbor and the peace after the war brought an end to the construction, and the partial hull was sold on the stocks in 1883.
- - the first American ship to bear the name was a New Orleans-class (1896) protected cruiser that was commissioned in 1898, decommissioned in 1922, and served during both the Spanish-American War and World War I.
- - the second ship to bear this name was a New Orleans-class (1931) heavy cruiser commissioned in 1934, decommissioned in 1947, and saw much service in World War II.
- - the third ship to bear this name was an Iwo Jima-class amphibious assault ship commissioned in 1968 and decommissioned in 1997. She was a recovery ship for Project Apollo and was used in the filming of the movie Apollo 13.
- - the fourth ship to bear this name is a San Antonio-class amphibious transport dock that was commissioned in 2004.
- CSS New Orleans was a floating gun battery on the Mississippi River in the service of the Confederate States of America.
