"I Could Have Danced All Night" is a song from the musical My Fair Lady, with music written by Frederick Loewe and lyrics by Alan Jay Lerner, published in 1956. The song is sung by the musical's heroine, Eliza Doolittle, expressing her exhilaration and excitement after an impromptu dance with her tutor Henry Higgins - in the small hours of the morning. In a counterpoint during the second of 3 rounds, two maids and the housekeeper, Mrs. Pearce, urge Eliza to go to bed, but she ignores them.

Hit versions of the song were recorded by Frank Sinatra, Sylvia Syms, Dinah Shore, Angélica María, Ben E. King as an ATCO single, Rosemary Clooney and Jamie Cullum.
