Jason X is a 2001 American science fiction slasher film directed by Jim Isaac and written by Todd Farmer. The tenth installment in the Friday the 13th franchise and a sequel to Jason Goes to Hell: The Final Friday (1993), it stars Lexa Doig, Lisa Ryder, Chuck Campbell, and Kane Hodder in his fourth and final appearance as Jason Voorhees. In the film, Jason is cryogenically frozen for over 400 years and awakens in 2455, after being found by a group of students, whom he subsequently stalks and kills one by one.

While other films of the franchise approach Jason as a human serial killer or undead monster, this movie views him through a science-fiction lens (referring to his inability to die as a "regenerative" power that can be studied and perhaps replicated) and then has him transformed by future-technology into a cyborg. This cyborg incarnation has been called Jason X in tie-in media, but is also often referred to by fans as "Uber Jason", a nickname the art design team and production crew used and which appeared in later comic books Jason X Special and Friday the 13th: Jason vs. Jason X. When conceiving the film, Todd Farmer came up with the idea of sending Jason into space, suggesting to the studio that it was the only direction left for the series. Kane Hodder called into the Howard Stern Show on May 1, 2002, and shared "I was a little hesitant about (the plot) the first time I heard the story too."

Jason X was theatrically released in the U.S. on April 26, 2002. It was negatively received by critics, and underperformed at the box office, grossing only $17.1 million on a budget of $11–14 million.
