Riley Anthony Winton Rudd (24 April 1924 – 29 May 2017) was an English stockbroker who found success in the world of technology start-ups, but came under censure from the Department of Trade and Industry for his business practices.

Among those who worked for him were Michael Spencer, founder of Icap, Brian Griffiths who became head of policy for Margaret Thatcher, and Tony "the animal" Parnes who became embroiled in the Guinness scandal.

Rudd enjoyed success as the broker to technology companies including Racal Electronics, Rotork and Plessey but the onset of blindness forced him to give up stockbroking in 1981.

[8] Tony Rudd turned to venture capitalism but came under increasing scrutiny from the Department of Trade and Industry (DTI) and in the satirical current affairs magazine Private Eye over his business practices.

[9] The extent to which he continued to be involved in the day-to-day running of the family investment vehicle, despite his daughter Amber's becoming the director at the age of 24, was raised in the press when her political career took off.

[3] Rudd owned a townhouse in Kensington, and Chalcot House near Bath where in later life he and his wife entertained a circle of political and business friends including Peter Walker, Arnold Weinstock and Alan Clark.
