Little Girl Blue is a popular song published in 1935, with music by Richard Rodgers and lyrics by Lorenz Hart. Its original performance was by Gloria Grafton, who introduced it in the Broadway musical Jumbo. The song is regarded as both a pop and a jazz standard, and it has been used in several films. It appears in The Jackpot (1950) and in The Handmaid's Tale (1990). In Billy Rose's Jumbo (1962) it is sung by Doris Day, and in Saint Omer (2022) by Nina Simone.
Recordings of the song include versions by Ella Fitzgerald (1956), Judy Garland (1957), Johnny Hartman (1959), Sam Cooke (1961), Doris Day (1962) and Nina Simone. Nina Simone is thus named both as the artist of a recording and as the singer in the 2022 film.
