"Mr. Sandman" is a popular song written by Pat Ballard and published in 1954. It was first recorded in May of that year by Vaughn Monroe & his orchestra and later that year by The Chordettes and the Four Aces. The song's lyrics convey a request to "Mr. Sandman" to "bring me a dream" – the traditional association of the folkloric figure. The pronoun used to refer to the desired dream is often changed depending on the sex of the singer or group performing the song, as the original sheet music publication, which includes male and female versions of the lyrics, intended.

The Chordettes were an American female vocal quartet, specializing in traditional pop music. They are best known for their 1950s hit singles "Mr. Sandman" and "Lollipop", both of which sold over a million copies.
