William Willingham, known as Bill Willingham, is an American writer and artist of comics. He was born in December 1956 in Fort Belvoir, Virginia. He is renowned for his work on the series Elementals and Fables.

In the late 1970s to early 1980s, he drew fantasy ink pictures for the Dungeons & Dragons Basic and Expert game rulebooks. He first gained attention for his 1980s comic book series Elementals published by Comico, which he both wrote and drew. For reasons unknown, the series had trouble maintaining an original schedule, and his position in the industry remained spotty for many years.

Willingham contributed stories to Green Lantern and started his own independent, black-and-white comics series Coventry, which lasted only 3 issues. He also produced the pornographic series Ironwood for Eros Comix. In the late 1990s, Willingham reestablished himself as a prolific writer, producing the 13-issue Pantheon for Lone Star Press.
