Wehrmacht was a U.S. band from Portland, Oregon, which was formed in the mid-1980s.

While they were influenced by the likes of Slayer, Van Halen, Kiss, and various punk/hardcore bands, they played speed metal. This was accomplished for the most part by drummer Brian Lehfeldt's technical proficiency and speed in conjunction with guitarist Marco Zorich's fast alternately picked, muted E-string. Marco could take the most sedate country/western (or Kiss) chord/riff, turn it upside-down, "blurr it" and turn it into an intense riff. While Marco played extremely fast rhythm, Wehrmacht's other guitarist, John Duffy, brought a fluid lead style that, as opposed to Kerry King's "hit every note on the neck as fast as possible and see what happens" style, was actually in key. His not over done use of the tremolo was the perfect foil to Marco's speed.

There have been rumors of Brian Lehfeldt trying to form a band called Biermacht from some of Wehrmacht's members.
