Michael Ryan Pritchard (born May 4, 1972) is the bassist for the punk band Green Day. While at school, he would pretend to play the bass when unable to practice, making a noise of someone playing single notes, resulting in the onomotopoeia that he later adopted as his stage name.

Pritchard met Billie Joe Armstrong in 1982, a few months before Armstrong's father died. He first founded Sweet Children with Armstrong, and then Green Day in 1988. Some years before, Pritchard moved in with Armstrong because his adopted mother and sister moved away from Rodeo. Pritchard did not want to move away from his new found best friend and love for music.
