"Frederick" is a song written by Patti Smith, and released as the lead single from Patti Smith Group's 1979 album Wave.

The song is dedicated to Fred "Sonic" Smith, guitar player of the Detroit band MC5 and Smith's future husband.

The melody of "Frederick" is an homage to Bruce Springsteen's live arrangement of "Prove It All Night" from the then-recent Darkness Tour of 1978.

Smash Hits said, "Patti has been getting a lot of stick from her original admirers for 'selling out' and going pop.

This is an excellent sample of her new work with producer Todd Rundgren.
