"Paperback Writer" is a 1966 song recorded and released by the English rock band the Beatles. Written by Paul McCartney and John Lennon (credited to Lennon–McCartney), the song was released as the A-side of their eleventh single. The single went to the number one spot in the United States, United Kingdom, Ireland, West Germany, Australia, New Zealand and Norway. On the US Billboard Hot 100, the song was at number one for two non-consecutive weeks, being interrupted by Frank Sinatra's "Strangers in the Night".

"Paperback Writer" was the last new song by the Beatles to be featured on their final tour in 1966.

According to disc jockey Jimmy Savile, McCartney wrote "Paperback Writer" in response to a request from an aunt who asked if he could "write a single that wasn't about love". Savile said, "With that thought obviously still in his mind, he walked around the room and noticed that Ringo was reading a book. He took one look and announced that he would write a song about a book." In a 2007 interview, McCartney recalled that he started writing the song after reading in the Daily Mail about an aspiring author, possibly Martin Amis. The Daily Mail was Lennon's regular newspaper and copies were in Lennon's Weybridge home when Lennon and McCartney were writing songs.

The song's lyrics are in the form of a letter from an aspiring author addressed to a publisher. The author badly needs a job and has written a paperback book based on a book by a "man named Lear".

Aside from deviating from the subject of love, McCartney had it in mind to write a song with a melody backed by a single, static chord. "John and I would like to do songs with just one note like 'Long Tall Sally.' We got near it in 'The Word.'" McCartney claimed to have barely failed to achieve this goal with "Paperback Writer", as the verse remains on G until the end, at which point it pauses on C.
