Yesterday and Today is a studio album by the English rock band the Beatles. Released in the United States and Canada in June 1966, it was their ninth album issued on Capitol Records and twelfth American release overall. Typical of the Beatles' North American discography until 1967, the album contains songs that Capitol had withheld from its configurations of the band's recent EMI albums, along with songs that the group had released elsewhere on non-album singles. Among its 11 tracks are songs from the EMI albums Help! and Rubber Soul, and three new 1966 recordings that would appear on Revolver in countries outside North America.

The Beatles were an English rock band formed in Liverpool in 1960, comprising John Lennon, Paul McCartney, George Harrison and Ringo Starr. They are regarded as the most influential band of all time and were integral to the development of 1960s counterculture and the recognition of popular music as an art form. Rooted in skiffle, beat and 1950s rock 'n' roll, their sound incorporated elements of classical music and traditional pop in innovative ways. The band also explored music styles ranging from folk and Indian music to psychedelia and hard rock. As pioneers in recording, songwriting and artistic presentation, the Beatles revolutionized many aspects of the music industry and were often publicized as leaders of the era's youth and sociocultural movements.
