Willie Johnson (March 4, 1923 – February 26, 1995) was an American electric blues guitarist. He is best known as the principal guitarist in Howlin' Wolf's band from 1948 to 1953. His raucous, distorted guitar playing features on Howlin' Wolf's Memphis recordings of 1951–3, including the hit song "How Many More Years" (recorded May 1951). His early use of distortion marks him out as one of the pioneers of the electric guitar. Robert Palmer has also cited him as the originator of the power chord, in reference to his guitar playing on "How Many More Years". His guitar work is considered a distant ancestor of heavy metal music.
