John Stanier (born 2 August 1968 in Baltimore, Maryland) first came into the spotlight in 1989 as the drummer for the band Helmet. He is known for his speed, endurance, and precision as a performer.

Stanier grew up in Florida and is a veteran of the local hardcore music scene. He is known for having a drum corps background, but never actually marched a summer season. He played tenor drums for the Florida Wave Drum and Bugle Corps through a few years of their winter/spring camps. He studied orchestral percussion at the University of South Florida, but never took formal drumset lessons. Stanier cites Neil Peart as his biggest influence, though he hates double bass drumming. He has also been influenced by drummers such as John Bonham, Billy Cobham, Bill Bruford, Terry Bozzio, Carl Palmer, and Lenny White. Stanier's drumming with Helmet has been cited as a big influence on a new generation of rock drummers. He endorses Tama drums, and is also well known for his Zildjian K ride cymbal perched as high as it can go when playing with Battles.
