The Saddest Music in the World is a 2003 Canadian film directed by Guy Maddin. Budgeted at $3.8-million and shot over 24 days, the film marks Maddin's first collaboration with actor Isabella Rossellini.

Maddin and co-screenwriter George Toles based the film on an original screenplay written by British novelist Kazuo Ishiguro, from which they kept "the title, the premise and the contest – to determine which country’s music was the saddest" but otherwise re-wrote. Like most of Guy Maddin's films, The Saddest Music in the World is filmed in a style that imitates late 1920s and early 1930s cinema, with grainy black-and-white photography, slightly out-of-sync sound and expressionist art design. A few scenes are filmed in colour, in a manner that imitates early two-strip Technicolor.
