Dream of a Rarebit Fiend is a 1906 silent trick film directed by Edwin S. Porter for Edison Manufacturing Company. It is a seven-minute live-action film adaptation of the comic strip Dream of the Rarebit Fiend by American cartoonist Winsor McCay. The film was marketed as using several special effects in which "some of the photographic 'stunts' have never been seen or attempted before."

In 2015, the United States Library of Congress selected the film for preservation in the National Film Registry, finding it "culturally, historically, or aesthetically significant".
