"You've Seen the Butcher" is a song by the American alternative metal band Deftones.

It was the fourth and final single released from their sixth studio album, Diamond Eyes (2010).

To support funding for bassist Chi Cheng, the drumset and keyboard used in filming the music video were auctioned.

When the song reaches the bridge, blood starts pouring from the ceiling of the library, spraying both the band and the women.
