Sha Na Na was an American rock and roll and doo-wop revival group formed in 1969. The group performed a song-and-dance repertoire based on 1950s hit songs that both revived and parodied the music and the New York City street culture of the 1950s. After gaining initial fame for their performance at the Woodstock Music and Art Fair, made possible with help from their friend Jimi Hendrix, the group hosted Sha Na Na, a syndicated variety series that ran from 1977 to 1981.

Billing themselves as "from the Streets of New York", members were frequently outfitted in gold lamé or leather jackets and sported pompadour or ducktail hairdos. The group's name was taken from a series of nonsense syllables ("sha na na na, sha na na na na") in the song "Get a Job", originally recorded by the Silhouettes.

The final lineup featured original members Donny York and Jocko Marcellino, and longtime member Screamin' Scott Simon, who joined in 1970. Everyone else from the original band and TV show had since departed. Final band members included bassist Tim Butler, guitarist Randy Hill, drummer Ty Cox, and saxophone player Michael Brown.

Sha Na Na released their last regular album in 2006, although they subsequently released compilation albums. As of December 5, 2022, they announced that they would no longer tour.
