Donald Chaffey (5 August 1917 – 13 November 1990) was a British film director, writer, producer, and art director. Chaffey's film career began as an art director in 1947, and his directorial debut was in 1953. He remained active in the industry until his death in 1990 from heart failure. His 1973 film Charley One-Eye was entered into the 24th Berlin International Film Festival.
British director Don Chaffey began his career in the film industry in the art department at Gainsborough Pictures. He began directing in 1951, often working on films aimed at children. He branched out into television in the mid-'50s, turning out many of the best episodes of such classic series as Danger Man (1960), The Prisoner (1967) and The Avengers (1961). Although he worked in many film genres, his best work is generally acknowledged to be the crackerjack fantasy Jason and the Argonauts (1963). On the other hand, he was also responsible for the lugubrious, box-office disaster The Viking Queen (1967), one of the few productions from Hammer Films that lost money. In the late 1970s Chaffey traveled to the US and worked primarily there, often in made-for-TV movies.
