"Surf's Up" is a song recorded by the American rock band the Beach Boys that was written by Brian Wilson and Van Dyke Parks. It was originally intended for Smile, an unfinished Beach Boys album that was scrapped in 1967. The song was later completed by Brian and Carl Wilson as the closing track of the band's 1971 album Surf's Up.

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.
