Dream Street (1921) is a movie directed by D. W. Griffith, and starring Carol Dempster, Charles Emmett Mack, and Ralph Graves in a story about a love triangle set in London, and based on two short stories by Thomas Burke, "Gina of Chinatown" and "Song of the Lamp". The film, released by United Artists, was poorly received in its day and critics still consider it one of Griffith's worst films.

The silent version premiered on April 12, 1921 at the Central Theatre in New York City. On April 27, Griffith and Ralph Graves recorded their respective sound segments at Orlando Kellum's Photokinema office at 203 West 40th Street.

The premiere engagement of the sound version of Dream Street took place on May 2, 1921 at Town Hall in New York City with Griffith's introduction. On May 15, the film reopened, now also with two other short sound sequences — Ralph Graves singing, and background noise in a scene showing a craps game. Unfortunately, no other theaters could show the sound version of the film, since no other theaters had the Photokinema sound system installed.On Sunday, May 29, Dream Street opened at the Schubert-Crescent Theater in Brooklyn with a program of short films made in Phonokinema. However, business was poor, and the program soon closed.
