"You'll Never Know" is a popular song with music written by Harry Warren and the lyrics by Mack Gordon. The song is based on a poem written by a young Oklahoma war bride named Dorothy Fern Norris. The song was introduced in the 1943 movie Hello, Frisco, Hello where it was sung by Alice Faye. The song won the 1943 Academy Award for Best Original Song, one of nine nominated songs that year. It was also performed by Faye in the 1944 film Four Jills in a Jeep. The song is often credited as Faye's signature song. However, Faye never released a record of the ballad, and frequent later recordings of the song by other singers diminished her association with it.

The Sinatra and Haymes records were made during the 1942–1944 musicians' strike, an American Federation of Musicians strike against the recording companies.

The group backing Haymes, The Song Spinners, was actually given credit on the Haymes record.
