Sir Gerard Foliott Vaughan (11 June 1923 – 29 July 2003) was a British psychiatrist and politician, who reached ministerial rank during the Thatcher administration.
He was perhaps most famous for losing a battle of wills with the Campaign for Nuclear Disarmament's Joan Ruddock over the government's grant to the Citizens Advice Bureau, a battle that cost him his government post and permanently curtailed his political ambitions.
