William Green (1934 – 28 January 2001), was an artist who achieved attention in the late 1950s as a practitioner of Action painting. His work became known following a documentary film featuring his creation paintings by riding a bicycle over a surface saturated with bitumen. From about 1965, Green withdrew from the art scene as a reaction to negative publicity. He resumed his work in 1995. One of his works is in Tate Modern.
