William Erwin "Will" Eisner (March 6, 1917 – January 3, 2005) was an American cartoonist, writer, and entrepreneur.

In 1978, he popularized the term "graphic novel" with the publication of his book A Contract with God. He was an early contributor to formal comics studies with his book Comics and Sequential Art (1985). The Eisner Award was named in Eisner's honor, and is given to recognize achievements each year in the comics medium; he was one of the three inaugural inductees to the Will Eisner Comic Book Hall of Fame.
