"One After 909" (sometimes entitled "The One After 909" in early recordings) is a song by the English rock band the Beatles from their 1970 album Let It Be.

It was written by John Lennon, with input from Paul McCartney, and credited to their joint partnership.

[6] On 5 March 1963, the Beatles recorded a version of the song in five takes during the same session that produced their third single, "From Me to You", and its B-side "Thank You Girl".

James Apollo recorded a version of the song in 2010 for Mojo's 40th Anniversary recreation Let It Be Revisited.
