Hasil Adkins /heɪˈsoʊ/ (April 29, 1937 – April 26, 2005) was an American singer-songwriter and multi-instrumentalist. His genres include rock and roll, country, blues and more commonly rockabilly. He generally performed as a one-man band, playing guitar and drums at the same time.

Growing up in poverty in the midst of the depression, Adkins' spirited lifestyle is reflected in his music. His songs explored an affinity for chicken, sexual intercourse and decapitation, and were isolated in obscurity until being unearthed in the 1980s. The newfound success secured him a cult following, spawned the Norton Records label, and helped usher in the genre known as psychobilly.
