"Good Vibrations" is a psychedelic pop song by American rock group The Beach Boys. Composed and produced by Brian Wilson, the song's lyrics were written by Wilson and Mike Love.

Released as a single on October 10, 1966 (backed with the Pet Sounds instrumental "Let's Go Away For Awhile"), it was The Beach Boys' third U.S. number-one hit, reaching the top of the Billboard Hot 100 chart in December 1966, as well as being their first British chart-topper. Initiated during the sessions for the Pet Sounds album, it was not taken from or issued as a lead single for an album, but as a stand-alone single, and later placed on the album Smiley Smile eleven months after its release.

Wilson's publicist Derek Taylor described "Good Vibrations" as a "pocket symphony". It featured instruments unusual for a pop song, including prominent use of the cello and an electro-theremin. It is number six on Rolling Stone's list of the "500 Greatest Songs of All Time".^[1] The song "Good Vibrations" is part of the The Rock and Roll Hall of Fame's 500 Songs that Shaped Rock and Roll list.^[2]
