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 more than 150 books through 1976, as well as venturing into fine art during and after this time. Fantasy artist Frank Frazetta supposedly described Jones as "the greatest living painter" and she included the quote on her website, but the source of the quote is unknown and Frazetta denied ever having said it when asked.
