Stefan Kaufmann (born 4 August 1960) is a German drummer and guitarist, best known as a member of the heavy metal bands Accept and U.D.O.

He joined Accept as drummer early enough to appear on the cover photos for their debut album, but too late to record the drums for the album (that was done by Frank Friedrich).

[4] Stefan Kaufmann joined Accept's singer Udo Dirkschneider in his band U.D.O.

In June 2018, Stefan Kaufmann rejoined the band, but serving only as a temporary replacement for the festival appearances, including the SummerBreeze/Rockpalast, until a new guitarist would be announced.

He was also one of the first drummers to use Meinl cymbals when they first became widely manufactured and sold in the late 1970s.
