"Pet Sounds" is an instrumental by American rock band the Beach Boys from their 1966 album Pet Sounds. Composed by Brian Wilson, it was originally called "Run James Run", as Wilson intended it to be used as the theme of a James Bond film. It was then titled "Pet Sounds", the title of the album on which it appears. It is the second instrumental to feature on Pet Sounds, the other being "Let's Go Away for Awhile".

Pet Sounds is the eleventh studio album by the American rock band the Beach Boys, released on May 16, 1966 by Capitol Records. It was initially met with a lukewarm critical and commercial response in the United States, peaking at number 10 on the Billboard Top LPs chart. In the United Kingdom, however, the album was lauded by critics and reached number 2 on the Record Retailer chart, remaining in the top ten for six months. Promoted there as "the most progressive pop album ever", Pet Sounds was recognized for its ambitious production, sophisticated music, and emotional lyrics. It is now considered to be among the greatest and most influential albums in music history.
