The Pyramids were an American surf group from Long Beach, California, who formed in 1961. In early 1964, they made the Top 20 of the Billboard Hot 100 with their instrumental "Penetration." It proved to be the final major instrumental surf hit.

In July 1964, the group appeared in the American International Pictures' film Bikini Beach, coming onstage wearing Beatle wigs, which were lifted to reveal their shaved heads.
