Jeffrey Catherine Jones (January 10, 1944 – May 19, 2011) was an American artist whose work is best known from the late 1960s through the 2000s. Jones created the cover art for over 150 books through 1976, as well as venturing into fine art during and after this time. Fantasy artist Frank Frazetta called Jones “the greatest living painter”. Although Jones first achieved fame as simply Jeff Jones and lived for a time as a male, she later changed her name and transitioned to female.
