"God Is Dead?" is a song by heavy metal band Black Sabbath featured on the album 13. It is the first single from the album, and the first with Ozzy Osbourne since 1998's "Psycho Man" and "Selling My Soul" from Reunion. The song was released via an MP3 download on Amazon. It was also available as a free download to those who pre-ordered the full album on iTunes. The song in its entirety was posted on the official YouTube channel in promotion of this. Both the song title and figure on the single's cover, by Heather Cassils, are a reference to Friedrich Nietzsche, a German philosopher who is famous for saying that "God is dead. God remains dead. And we have killed him. How shall we comfort ourselves, the murderers of all murderers?".
"God Is Dead?" reached No. 6 on the UK Rock Charts.
