Stefan Schwarzmann (born 11 November 1965, Erlangen) is a German drummer who has recorded for Accept, U.D.O., Running Wild, X-Wild, Krokus and Helloween. Schwarzmann joined Helloween as a replacement for departing drummer Mark Cross in 2003. Although Stefan got on well with the members of the band, he had other musical preferences. As a result, he chose to leave Helloween after the Rabbits on the Run Tour in early 2005.
