Jonah Hex is a 2010 American post-Civil War Western film loosely based on the DC Comics character of the same name. Distributed by Warner Bros. Pictures, the film is directed by Jimmy Hayward and stars Josh Brolin as the title character, Jonah Hex, and also stars John Malkovich, Michael Fassbender, and Megan Fox. The film was released on June 18, 2010 to generally negative reviews from critics and audiences and flopped at the box office.

Jonah Woodson Hex is a fictional character, a Western comic book antihero created by writer John Albano and artist Tony DeZuniga and published by DC Comics. Hex is a surly and cynical bounty hunter whose face is horribly scarred on the right side. Despite his poor reputation and personality, Hex is bound by a personal code of honor to protect and avenge the innocent. The character is portrayed by Josh Brolin in the 2010 film adaptation of the same name. Thomas Jane provided his voice in a DC Animated short film.

The character first appeared in a full-page in-house ad for All-Star Western #10 which was published in various Nov/Dec 1971-dated DC comics, including a few of DC's war comics line, as well as a half-page version of the same house ad in Batman #237. This house ad contains the first published images of Jonah Hex, as well as two dialogue-filled comic strip panels not used in his first "full-story appearance".

In a 2010 interview with Filipino journalist Anna Valmero, DeZuniga described the moment he first conceived the image that would become Jonah Hex: "When I went to my doctor, I saw this beautiful chart of the human anatomy. And I saw the anatomy of the figure was split in half, straight from head to toe. Half his skeleton was there, half his nerves and muscles. That’s where I got the idea it won’t be too bad if his distortion would be half.”

Jonah (Hebrew: יוֹנָה, Modern Yona Tiberian Yônā ; dove; Arabic: يونس‎, Yūnus or يونان, Yūnān; Greek/Latin: Ionas) is the name given in the Hebrew Bible (Tanakh/Old Testament) to a prophet of the northern kingdom of Israel in about the 8th century BC, the eponymous central character in the Book of Jonah, famous for being swallowed by a fish or a whale, depending on translation. The Biblical story of Jonah is also repeated, with minor changes, in the Qur'an.

Jonah son of Amittai appears in 2 Kings as a prophet from Gath-Hepher (a few miles north of Nazareth) active during the reign of Jeroboam II (c.786-746 BC), where he predicts that Jeroboam will recover certain lost territories.
