Jack Thomas Chick was an American cartoonist and publisher, best known for his fundamentalist Christian "Chick tracts". He expressed his perspective on a variety of issues through sequential-art morality plays.

A tract is a literary work and, in current usage, usually religious in nature. The notion of what constitutes a tract has changed over time. By the early part of the 21st century, a tract referred to a brief pamphlet used for religious and political purposes, though far more often the former. Tracts are often either left for someone to find or handed out. However, there have been times in history when the term implied tome-like works. A tractate, a derivative of a tract, is equivalent in Hebrew literature to a chapter of the Christian Bible.
