"Eleanor Rigby" is a song by the English rock band the Beatles from their 1966 album Revolver. It was also issued on a double A-side single, paired with "Yellow Submarine". The song was written primarily by Paul McCartney and credited to Lennon–McCartney.

The song continued the transformation of the Beatles from a mainly rock and roll- and pop-oriented act to a more experimental, studio-based band. With a double string quartet arrangement by George Martin and lyrics providing a narrative on loneliness, "Eleanor Rigby" broke sharply with popular music conventions, both musically and lyrically. Richie Unterberger of AllMusic cites the band's "singing about the neglected concerns and fates of the elderly" on the song as "just one example of why the Beatles' appeal reached so far beyond the traditional rock audience".
