SS Andrea Doria was an Italian ocean liner, or passenger ship. It was owned by a ship line called the Italian Line. It was said by many to be the biggest, fastest, safest, and most beautiful ship in Italy after World War II. It could carry 1,221 passengers and 563 crew.

The ship was built by the Ansaldo Shipyards in Genoa, Italy. It was launched on June 16, 1951. Its maiden voyage, or first voyage, was on January 14, 1953. Three years later in 1956, it crashed with another ship, MS Stockholm, in the Atlantic Ocean. At that time, 1,134 passengers and 572 crew were on board. Andrea Doria sank in 11 hours, but Stockholm survived. 

The Andrea Doria was the last large ocean liner to sink before airplane travel became popular.
