A ship replica is a reconstruction of a no longer existing ship. Replicas can range from authentically reconstructed, fully seaworthy ships, to ships of modern construction that give an impression of a historic vessel. Some replicas may not even be seaworthy, but built for other educational or entertainment purposes.

Andrew Doria was a brig purchased by the Continental Congress in November 1775. She is most famous for her participation in the Battle of Nassau—the first amphibious engagement by the Continental Navy and the Continental Marines—and for being the first United States vessel to receive a salute from a foreign power.
