Dawn Addams (21 September 1930 – 7 May 1985) was a British actress in motion pictures of the 1950s.
Her film career began in 1951, and a year later she co-starred with Peter Lawford in The Hour of 13.
In 1953 she appeared in a small role in the ground-breaking film The Moon is Blue, the film which helped end the system of religious censorship of Hollywood films, which had been in place since 1934.
She also embarked on a USO tour the same year to help entertain troops in Korea, followed by a small but heavily publicised role as Richard Carlson's model girlfriend in the science fiction film Riders to the Stars (1954).
Another notable performance was as the female lead opposite actor-director-filmmaker legend Charlie Chaplin in his final comedy to star himself A King in New York (1957).
During the 1960s and 1970s she appeared mainly in British TV shows and French movies.
She was a semi-regular on the instructional series En France (1962) and the campy sci-fi serial Star Maidens (1977), and she was a ubiquitous leading lady in several episodes of The Saint, which starred Roger Moore as Simon Templar (1962 - 1969).
