SS Minnedosa was one of a pair of transatlantic steam ocean liners that were built in the United Kingdom, launched in 1917 and operated by Canadian Pacific until 1935.

In 1913 Hamburg America Line ordered a pair of liners from Barclay, Curle & Co. Due to the outbreak of the First World War, Canadian Pacific (CP) bought the two partly built ships and had them completed[1] to its specification.

A pair of four-cylinder triple-expansion steam engines drove her port and starboard screws.

[1] On 5 December 1918 Minnedosa began her maiden voyage from Liverpool to St John, New Brunswick, repatriating troops of the Canadian Expeditionary Force.

[1] After trooping duties, Minnedosa began civilian service between Liverpool and Canada.

[9] For a period in the 1920s Minnedosa's Master was Captain Ronald Stuart, VC, which entitled her to fly the Blue Ensign.

[12] This clause was breached when the pair were passed to Flotte Riuniti Cosulich-Lloyd Sabaudo, who had them refitted as troop ships for the Italian Government.

[1] On 17 November 1942 the submarine HMS Umbra torpedoed Piemonte off Capo Rasocolmo in the Mediterranean.
