Charles Frederick Wilson (30 June 1932 – 23 April 1990) was an English career criminal. A member of the Great Train Robbery gang, of which he was treasurer. He was shot dead on the doorstep of his Marbella home in 1990.

Wilson was born on 30 June 1932 to Bill and Mabel Wilson in Battersea, London. Of heavy build and handsome appearance, with piercing blue eyes, Wilson was, from an early age, an intimidating presence. He soon befriended many known or would-be criminals. His friends from childhood included Jimmy Hussey, Tommy Wisbey, Bruce Reynolds and Gordon Goody. Later on, he met Buster Edwards and two car thieves, Mickey Ball and Roy James.

From 1948 to 1950 he undertook National Service. In 1955 he married Patricia (Pat) Osbourne, with whom he had three children.

Wilson turned to crime early in life and spurned his father's legitimate but low-income wage. While he did have legitimate work in his in-laws' grocer's shop, he also was a thief and his criminal proceeds went into buying shares in various gambling enterprises. He went to jail for short spells for numerous offences.

In 1960, Wilson began to work with Reynolds and planned to get into the criminal big league. In 1962, a gang led by Reynolds stole £62,000 in a security van robbery at London Heathrow Airport. They then robbed a Royal Mail train at Swindon, which netted £700. But Reynolds, looking for his career-criminal defining moment, started planning his next train robbery over a period of three months.

Reynolds organised a gang of 17 men to undertake the 1963 Great Train Robbery. Wilson was the gang's treasurer who gave the robbers their cut of the haul: £150,000 each. He was soon captured, and during the trial at Aylesbury Assizes in April 1964 he was given the nickname "the silent man" as he refused to say anything at all. Sentenced to 30 years imprisonment, he was held at HMP Winson Green, where after just four months on 12 August 1964, he arranged for a three-man gang to break in and facilitate his escape.

Wilson and his family settled in Rigaud, Quebec, Canada, situated 70 kilometres (43 mi) west of Montreal and 130 kilometres (81 mi) east of Ottawa. For Christmas 1964, the family travelled to Acapulco to join Reynolds and Edwards, who had not been caught. Reynolds and his family later moved to Montreal, but a proposed theft of Canadian dollars with Wilson was prevented by Royal Canadian Mounted Police observation. Reynolds moved to Vancouver, before returning that summer to the South of France.

Having successfully evaded re-capture for four years, Wilson was caught on 24 January 1968, after his wife telephoned her parents in England, thus enabling Scotland Yard to track them down. Returning to England, Wilson served 10 more years in the train robbers secure unit at HMP Durham.
