Convoy Faith was a small, fast Allied convoy of World War II. It suffered heavy casualties when attacked by German long-range bombers while en route from Britain to West Africa in July 1943. The convoy comprised two large troopships and a freighter, later joined by two destroyers and two frigates as escorts at various dates after it sailed on 7 July 1943. The two troopships, SS California and SS Duchess of York, both former liners, were carrying military personnel to West Africa, where locally recruited troops were to be embarked as reinforcements for the Allied forces in Burma and the Middle East. The freighter MV Port Fairy, carrying ammunition, was ultimately bound for Australia and New Zealand via the Panama Canal.

SS Duchess of York 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.
