Stephen Whittaker (28 June 1947 – 7 February 2003) was a British actor and director. He worked largely in British film and television, and attended Henley-in-Arden School in Warwickshire before further training as an actor at London's Corona Academy. He began his career aged 17, as a "bad boy" in the film To Sir With Love (1966), and in the classic BBC Doctor Who adventure The Web of Fear, as a soldier battling Yeti in the London Underground.

In 1985, Whittaker took a director's training course and directed a short training film, which he sent to John Schlesinger (who had directed him in Yanks). Schlesinger suggested him to producer Mark Shivas as director for Channel 4's drama trilogy What If It's Raining?, written by Anthony Minghella. This was the beginning of a directing career of prestigious TV and film work. Shortly before Whittaker's death, writer Julian Fellowes spoke of him as "the most exciting director in the industry."
