"Hush, Hush, Sweet Charlotte" is a popular song with music by Frank De Vol and lyrics by Mack David, introduced in the 1964 film Hush... Hush, Sweet Charlotte starring Bette Davis. The song's title appears with varying punctuation in its different versions: this article indicates how each specific version styled the title.

Originally, the film and the song did not share a title, the working title of the film being What Ever Happened to Cousin Charlotte? Reportedly, Bette Davis disliked the working title feeling it falsely indicated a sequel to What Ever Happened to Baby Jane? and, the song with the opening lyric "Hush, hush, sweet Charlotte" having been written early in the film's development and having been played for Davis, she suggested Hush... Hush, Sweet Charlotte should serve as the movie's title.

In the storyline of the film, the song is written for Davis' character: the aging Southern belle Charlotte Hollis, by her would-be lover John Mayhew whose murder thirty-seven years ago is generally ascribed to Charlotte. The song also effectively functions as the film's theme as its lyrics in effect reference how Charlotte will obsess over her lost love throughout most of her life. The song's melody plays on a music box which Charlotte treasures, and is also a feature of the gaslighting to which Charlotte's subjected, as she hears the song played on the harpsichord while she tries to sleep. Davis as Charlotte is also seen playing the song on the harpsichord and singing the most lyrically complete version of the song heard in the film, the Al Martino recording of the song only being heard for one chorus under the film's closing credits. The "Hush... Hush, Sweet Charlotte" song is heard in full as an instrumental - by the Frank DeVol Orchestra - under the film's opening credits, just prior to which a group of juvenile tormentors sing a debased version of the chorus, referencing Charlotte's supposed murder of John Mayhew.
