All Summer Long is the sixth album by the American rock band the Beach Boys, released July 13, 1964 on Capitol Records. Regarded as their first artistically unified collection of songs, as well as one of the first true concept albums, it marked the Beach Boys' first LP that was not focused on themes of cars or surfing. Instead, the songs are semi-autobiographical and relate to the experiences of a typical Southern Californian teenager, a theme encapsulated by the title track, "All Summer Long", and the often-imitated front cover, a modernist style photo collage depicting the band members fraternizing with young women on a beach.

The Beach Boys are an American rock band formed in Hawthorne, California, in 1961. The group's original lineup consisted of brothers Brian, Dennis, and Carl Wilson, their cousin Mike Love, and friend Al Jardine. Distinguished by their vocal harmonies, adolescent-oriented lyrics, and musical ingenuity, they are one of the most influential acts of the rock era. They drew on the music of older pop vocal groups, 1950s rock and roll, and black R&B to create their unique sound. Under Brian's direction, they often incorporated classical or jazz elements and unconventional recording techniques in innovative ways.
