Duncan Alexander Croall Scott-Ford (4 September 1921 – 3 November 1942) was a British merchant seaman who was hanged for treachery after giving information to an enemy agent during the Second World War.

In June 1939 Scott-Ford was serving on the light cruiser HMS Gloucester when she called at Dar-es-Salaam in the Tanganyika Territory on a goodwill visit.

Rithman offered Scott-Ford 1,000 Portuguese escudos if he would confirm the rumour that all British ships had been ordered to be in port on 28 June 1942.

Scott-Ford confessed to not having found the information Rithman wanted, but the group nevertheless discussed issues such as the state of morale in the United Kingdom, the extent of air raid damage there, and public opinion of Prime Minister Winston Churchill.

His ship departed Lisbon the next day; all the crew were interrogated on arrival at Liverpool to ask if they had been approached by German agents.

Scott-Ford did give details of the convoy he had sailed in and its protection, the location of an aircraft factory, and the training of troops for an invasion of Europe.

He was sent to Camp 020, an interrogation centre based at Latchmere House on Ham Common in southwest London where he complied with the authorities, although he became increasingly alarmed as he began to understand the seriousness of his situation.

Professor A. W. B. Simpson, a historian of detention without trial, has speculated that Scott-Ford was offered his life in return for additional information on the Germans' intelligence system, but had no more to give.

Scott-Ford was charged under the Treachery Act 1940, and after an in camera trial before Mr Justice William Norman Birkett, was convicted on 16 October 1942.
