A Nightingale Sang in Berkeley Square is a 1979 British heist film directed by Ralph Thomas, written by Guy Elmes and starring Richard Jordan, Oliver Tobias and David Niven. It is subtitled "based on one of the biggest robberies in London". The film takes its name from the 1940 published song "A Nightingale Sang in Berkeley Square".

Ralph Thomas later said the film "had quite a superb cast" and "he was really quite fond" of the movie "but I didn't do it as well as I should have done because by the time we started it David was already sick, and so we had to do the best we could as quickly as we could and it didn't come off as I'd hoped. But it was still a fun film and we enjoyed making it."It was shot at Twickenham Studios and on location around London. The film's sets were designed by the art director Lionel Couch.
