Lydia Lunch (born Lydia Anne Koch, June 2, 1959) is an American singer, poet, writer, actress and self-empowerment speaker. Her career was spawned by the New York City no wave scene.

Her work typically features provocative and confrontational noise music delivery, and has maintained an anti-commercial ethic, operating independently of major labels and distributors. The Boston Phoenix named Lunch one of the ten most influential performers of the 1990s. Her collaboration with Sonic Youth called “Death Valley ’69” was named one of “The 50 Most Evil Songs Ever” by Kerrang!
