"She Came In Through the Bathroom Window" is a song by the English rock band the Beatles from their 1969 album Abbey Road. Written by Paul McCartney and credited to Lennon–McCartney, it is the fifth song of the album's climactic medley, immediately following "Polythene Pam".

Abbey Road is the eleventh studio album by the English rock band the Beatles, released on 26 September 1969. It is the last album the group recorded, although Let It Be was the last album completed before the band's break-up in April 1970. It was mostly recorded in April, July, and August 1969, and topped the record charts in both the United States and the United Kingdom. A double A-side single from the album, "Something" / "Come Together", was released in October, which also topped the charts in the US.
