Harold Anthony LeDoux (November 7, 1926 – June 7, 2015) was an American artist best known for his work on the newspaper comic strip Judge Parker.

While in the Merchant Marine during World War II, LeDoux saved enough money to be able to attend the Chicago Academy of Fine Arts.

Arriving in New York City, he began contributing to the Famous Funnies comic books.

"[4] It may be that he was ghosting for or was supervised by Heilman in a studio arrangement, both common circumstances in comic strip history.

[5] In any case, it was not until 1965 that LeDoux was credited as artist on the strip, as Heilman relinquished the title to pursue another project (he died shortly after).
