"We Can Work It Out" is a song by the English rock band the Beatles, written by Paul McCartney and John Lennon. It was first issued as a double A-side single with "Day Tripper" in December 1965. It also appeared on the 1966 US release Yesterday and Today. The release marked the first time in Britain that both tracks on an artist's single were promoted as joint A-sides. The song was recorded during the sessions for the band's Rubber Soul album. The single was number 1 in Britain (where it won the Ivor Novello Award for the top-selling A-side of 1965), the United States, Australia, Canada and Ireland. In the UK, it was the seventh highest selling single of the 1960s.

"We Can Work It Out" is a comparatively rare example of a Lennon–McCartney collaboration from this period in the Beatles' career, in that it recalls the level of collaboration the two songwriters had shared when writing the group's hit singles of 1963. This song, "A Day in the Life", "Baby, You're a Rich Man" and "I've Got a Feeling", are among the notable exceptions.
