MS Stockholm was the name of two near-identical ocean liners built by Cantieri Riuniti dell' Adriatico, Monfalcone, Italy between 1936 and 1941 for the Swedish American Line.

The second ship served for three years in the Regia Marina and Kriegsmarine under the name MS Sabaudia, until sunk by British bombers outside Trieste in 1944.

[8] In November 1936 the Swedish American Line placed an order for the new Stockholm at Cantieri Riuniti dell' Adriatico, Italy, with the delivery date projected to be in March 1939.

Eventually the large amounts of water pumped on the ship caused her to lose stability and sink in her berth.

[4][6] She completed her trial runs in the Swedish American Line livery, but ultimately the company saw no point in taking delivery of the vessel—the war had caused transatlantic services to be suspended, and it was possible that the ship could not even be safely transferred to neutral Sweden from Italy.

[11] As a result, the Stockholm was sold to the Italian government on 3 November 1941, renamed MS Sabaudia and converted to a troopship.

Most sources claim that she was used as a troopship by the Regia Marina without specifying the campaigns she participated in,[1][3][6] while others state she was simply laid up at Trieste after conversion.

On the Stockholm this construction was used to perhaps an even greater practicality than on her predecessors, with the author Philip Dawson praising her interior layout as being "remarkably straightfordward" and stating she would have been "a great success" had she ever entered commercial service.
