Terrifier 3 is a 2024 American Christmas supernatural slasher film written, edited, and directed by Damien Leone. It is the sequel to Terrifier 2 (2022) and the third installment in the Terrifier film series. The film stars David Howard Thornton, Lauren LaVera, Elliott Fullam, and Samantha Scaffidi. On the days leading up to Christmas, Sienna Shaw attempts to rebuild her life, while pursued by Art the Clown alongside his new accomplice, a possessed Victoria Heyes.

Following the critical and commercial success of Terrifier 2, Leone began writing for the third film with plans for an overarching narrative. Leone wanted to feature Victoria more prominently, as he regretted leaving the character underdeveloped in the first film. Principal photography began in February 2024 on a $2 million budget, and wrapped that April.

Terrifier 3 premiered at Fantastic Fest on September 19, 2024, and was theatrically released in the United States on October 11, by Cineverse and Iconic Events Releasing. The film received generally positive reviews from critics and was a massive box office success, grossing $84 million worldwide and becoming the highest-grossing unrated film of all time.
