"You'll Never Walk Alone" is a show tune from the 1945 Rodgers and Hammerstein musical Carousel. In the second act of the musical, Nettie Fowler, the cousin of the protagonist Julie Jordan, sings "You'll Never Walk Alone" to comfort and encourage Julie when her husband, Billy Bigelow, the male lead, stabs himself with a knife whilst trying to run away after attempting a robbery with his mate Jigger and dies in her arms. The song is reprised in the final scene to encourage a graduation class of which Louise is a member. The now invisible Billy, who has been granted the chance to return to Earth for one day in order to redeem himself, watches the ceremony and is able to silently motivate Louise and Julie to join in with the song.

Rodgers and Hammerstein was a theater-writing team of composer Richard Rodgers (1902–1979) and lyricist-dramatist Oscar Hammerstein II (1895–1960), who together created a series of innovative and influential American musicals. Their musical theater writing partnership has been called the greatest of the 20th century.
