RMS Duchess of Atholl was one of a class of four steam turbine ocean liners built in Glasgow in 1927–29 for Canadian Pacific Steamships Ltd's transatlantic service between Britain and Canada. In the Second World War she was converted into a troop ship. In 1942 a U-boat sank her in the South Atlantic, killing four of Duchess of Atholl's crew, whilst 821 survivors were rescued.
