"Do You Want to Know a Secret" is a song by English rock band the Beatles from their 1963 album Please Please Me, sung by George Harrison. In the United States, it was the first top ten song to feature Harrison as a lead singer, reaching No. 2 on the Billboard chart in 1964 as a single released by Vee-Jay, VJ 587. In the UK, Billy J. Kramer released a cover of the song as his debut single, reaching No. 1 on the NME singles chart and No. 2 on the Record Retailer chart.

"Do You Want to Know a Secret", written in autumn 1962, was primarily composed by John Lennon but credited to Lennon–McCartney.^[2] The 1963 version by Billy J. Kramer with the Dakotas (a UK No. 2) credited the composition to "McCartney–Lennon". The song was inspired by "I'm Wishing",^[3] a tune from Walt Disney’s 1937 animated film Snow White and the Seven Dwarfs which Lennon's mother, Julia, would sing to him as a child. The first two lines of the song in Disney's movie ("Want to know a secret? Promise not to tell?") come right after the opening lyrics ("You'll never know how much I really love you... You'll never know how much I really care...").^[4][5] McCartney has said it was a "50–50 collaboration written to order", i.e., for Harrison to sing,^[6] but Lennon, who always claimed the song as his own, explained in a 1980 interview that he had realized as soon as he had finished writing the song that it best suited Harrison.^[7]

In 1980, Lennon said that he gave "Do You Want to Know a Secret" to Harrison to sing because "it only had three notes and he wasn't the best singer in the world", but added "he has improved a lot since then."^[5] The song was recorded as part of their marathon ten-hour recording session on 11 February 1963 along with nine other songs for Please Please Me.^[8] Harrison sang two songs on Please Please Me—this song by Lennon–McCartney and "Chains" by Goffin/King. "Don't Bother Me" would be Harrison's debut composition and appeared on the Beatles' next UK album With the Beatles.^[9]

Harrison and Lennon both played acoustic guitars on the recording in different channels – on the stereo mix, Harrison's guitar was panned to the right channel while Lennon's was panned to the left.^[10]

"Do You Want to Know a Secret" was released a year later as a single by Vee-Jay in the United States on 23 March 1964, reaching the number two spot behind "Hello, Dolly!" by Louis Armstrong in Billboard, reaching number three on the Cash Box chart, but reaching number one for two weeks in the chart published by the Teletheatre Research Institute. In the U.S., it was the most successful Beatles song on which Harrison sang lead vocal until "Something" peaked at No. 1 as part of a double-sided number one hit with "Come Together" in 1969.
