The Mean One is a 2022 American Christmas slasher film directed by Steven LaMorte from a screenplay written by Flip and Finn Kobler. It is an unlicensed parody of Dr. Seuss' 1957 children's book How the Grinch Stole Christmas! and its adaptations, and stars Krystle Martin, Chase Mullins, John Bigham, Erik Baker, Flip Kobler, and Amy Schumacher, with David Howard Thornton as the eponymous character. It follows a young woman as she attempts to defend her childhood town from a green-skinned creature who goes on a murderous rampage during the holiday season.

The film was first announced by XYZ Films in October 2022, who collaborated with A Sleight of Hand Productions, Amy Rose Productions and Kali Pictures on its production. Because it is unauthorized, the film never uses the language of the original book. The Mean One was released by Atlas Film Distribution theatrically on December 9, 2022 and received generally negative reviews.
