David Randall Blythe (born February 21, 1971) is an American vocalist, best known as the lead singer and lyricist of heavy metal band Lamb of God. He has also performed guest vocals for Cannabis Corpse, Overkill, Gojira, Eyehategod, Eluveitie, Bad Brains, Soulfly, Clutch, Suicide Silence, Doyle (band), and Voodoo Glow Skulls, and is the lead singer of side-project band Halo of Locusts.

In June 2012, Blythe was arrested in the Czech Republic and was indicted on manslaughter charges related to the 2010 death of Daniel Nosek, a 19-year-old fan, after a Lamb of God concert. The Czech court found that Blythe had pushed the fan off the stage and was « morally responsible » for the killing, but held that liability for Nosek’s death also lay with promoters and security members, and ultimately acquitted Blythe of the criminal charges specifically.

After his acquittal, Blythe recorded the album VII: Sturm und Drang with Lamb of God, an album inspired by the manslaughter case and his detention time in the Czech Republic.
