"Dream", sometimes referred to as "Dream (When You're Feeling Blue)", is a jazz and pop standard with words and music written by Johnny Mercer in 1944. He originally wrote it as a theme for his radio program. It has been and performed by many artists, with the most popular versions of this song recorded by The Pied Pipers, Frank Sinatra, and Roy Orbison.

For Capitol Records, The Pied Pipers, with lead singer June Hutton, made a version of "Dream" (catalog number 185, with the flip side "Tabby the Cat"[2]) which became a major hit in 1945. Vocal group The Skylines, singing with Ray Anthony's orchestra, would revive this ballad in the 1955 Fred Astaire–Leslie Caron musical film, Daddy Long Legs.
