"One I've Been Missing" is a song by British girl group Little Mix.

[1] It was co-written by Little Mix member Leigh-Anne Pinnock alongside Jez Ashurst, Rachel Furner, Sinéad Harnett, and Tre Jean-Marie.

One I've been missing has been described as a 1950s inspired Ballad with a beautiful ode to festive love, with luscious harmonies.

It was later added onto the expanded edition of their sixth studio album, Confetti as a bonus track.
