Smiley Smile is the 12th studio album by the American rock band the Beach Boys, released on September 18, 1967. Conceived as a simpler and more relaxed version of their unfinished Smile album, Smiley Smile is distinguished for its homespun arrangements, "stoned" aesthetic, and lo-fi production. Critics and fans generally received the album and its lead single, "Heroes and Villains", with confusion and disappointment. The album reached number 9 on UK record charts, but sold poorly in the U.S., peaking at number 41—the band's lowest chart placement to that point.

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.
