Thanksgiving is a 2023 American slasher film directed by Eli Roth and written by Jeff Rendell, based on a story by the pair, who produced with Roger Birnbaum.

The film stars Patrick Dempsey, Addison Rae, Milo Manheim, Jalen Thomas Brooks, Nell Verlaque, Rick Hoffman, and Gina Gershon, and follows a small Massachusetts town that is terrorized by a killer in a John Carver mask around the Thanksgiving holiday.

Thanksgiving received a theatrical release in the United States by TriStar Pictures on November 17, 2023. The film received generally positive reviews from critics and has grossed $46 million worldwide. A sequel is in development.
