Jason Goes to Hell: The Final Friday is a 1993 American supernatural slasher film directed by Adam Marcus from a screenplay by Dean Lorey and Jay Huguely, based on a story by Huguely and Marcus. The ninth installment in the Friday the 13th franchise, as well as the first installment in the franchise to be released by New Line Cinema, it stars John D. LeMay, Kari Keegan, Erin Gray, Allison Smith, Steven Culp, Steven Williams, and Kane Hodder as Jason Voorhees, reprising his role from Friday the 13th Part VII: The New Blood (1988) and Friday the 13th Part VIII: Jason Takes Manhattan (1989). The film follows the ghost of Jason possessing people in order to continue his killings after his death. To resurrect himself, Jason must possess a member of his bloodline, but he can also be permanently killed by one of his family members using a magic dagger.

The film was conceived by co-writer and director Marcus under Sean S. Cunningham, producer and director of the first film. After the low box-office returns of Jason Takes Manhattan, Paramount Pictures sold the character rights of Jason Voorhees to New Line Cinema.

Jason Goes to Hell was theatrically released on August 13, 1993, and grossed $15.9 million at the box office on a budget of $3 million, becoming the second-lowest performing film in the series, after Jason Takes Manhattan. The film was lambasted by critics and fans, criticizing the supernatural elements and lack of Jason Voorhees as a physical character.

The next installment in the series, Jason X, was released in 2001, and a crossover sequel with the A Nightmare on Elm Street franchise, Freddy vs. Jason, was released in 2003.

At Crystal Lake, Jason Voorhees stalks a woman. The woman (an undercover FBI agent) leads Jason into a trap where FBI SWAT agents attack and kill him with a grenade launcher. Jason's remains are sent to a morgue, where his beating heart is eaten by the coroner, allowing Jason's soul to possess him. Jason, in the coroner's body, escapes the morgue, killing another coroner and two FBI guards.

Jason finds three teenagers at Crystal Lake and kills them. When two police officers are called to investigate, Jason kills one of them and possesses the other. Bounty hunter Creighton Duke discovers that only members of Jason's bloodline can permanently kill him, and he will return if he possesses a family member. The only living relatives of Jason are his half-sister Diana Kimble, her daughter Jessica, and Stephanie, the young daughter of Jessica and Steven Freeman.

Jason attempts to possess Diana but Steven stops him. Diana is killed, and Jason escapes. Steven is arrested for the murder of Diana. He meets Duke in prison, who gives Steven information about Jason and his connection with Jessica. Determined to get to Jessica before Jason, Steven escapes from prison. He goes to the Voorhees house to find evidence to convince Jessica of her link to Jason. Jessica's boyfriend, TV reporter Robert Campbell, receives a phone call in the house that Steven overhears, which reveals that Campbell is attempting to boost ratings by revealing Jason's return from death. Jason transfers his heart to him through their mouths. Now in Campbell's body, Jason leaves and attempts to possess Jessica. Steven stops him and tries to explain everything to Jessica, but she does not believe him and goes to the police station without him.

Jason arrives and kills the officers while searching for Jessica, who he nearly possesses before Steven stops him again. Duke escapes from his cell in the resulting chaos. Now believing Steven, Jessica goes with him to the diner to get Stephanie. Jason arrives and is attacked by the owners and a waitress. Jessica and Steven discover that Duke has Stephanie, and he demands that Jessica meet him at the Voorhees house alone.
