"Wham Bam" is a 1976 pop hit by the American group Silver, written by country songwriter Rick Giles. It was the only charting song by the group. Lead vocals are by John Batdorf.

The single's title, "Wham Bam", was shown as "Wham Bam Shang-A-Lang", and peaked at #16 on the US Billboard Hot 100 in the fall of 1976. It is ranked as the 70th biggest hit of 1976. The song also charted in Canada (#27), doing better on the Adult Contemporary chart (#17).

Arista executives gave the band the song to record, after concluding that none of the other tracks on the album they produced had single potential. Arista head Clive Davis himself co-produced their sole album.

Chicago radio superstation WLS, which gave "Wham Bam" much airplay, ranked the song as the 80th biggest hit of 1976. It peaked at number eight on their surveys of October 23 and 30, 1976.

The song appears in the 2017 Marvel Studios sequel film, Guardians of the Galaxy Vol. 2, and it is included on the movie's soundtrack.
