Terrifier 3 is a 2024 American Christmas supernatural slasher film written and directed by Damien Leone and starring Lauren LaVera, David Howard Thornton, Elliott Fullam, Samantha Scaffidi, Antonella Rose, Margaret Anne Florence, and Bryce Johnson. On the days leading up to Christmas, the story follows Sienna Shaw as she attempts to rebuild her life. At the same time, Art the Clown is pursuing her alongside his new accomplice, a possessed Victoria Heyes. It is the sequel to Terrifier 2 (2022) and is the third installment in the Terrifier franchise.

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 in Austin, Texas, on September 19, 2024, and was theatrically released in the United States on October 11. The film received generally positive reviews from critics and has grossed $49.8 million, becoming the highest-grossing film of the franchise.
