Fear Street: Prom Queen is a 2025 American slasher film directed by Matt Palmer from a screenplay he co-wrote with Donald McLeary, loosely based on the novel The Prom Queen (1992) from the Fear Street book series. Produced by Chernin Entertainment, it is the fourth installment in the Fear Street film series. The film stars India Fowler, Suzanna Son, Fina Strazza, David Iacono, Ella Rubin, Chris Klein, Ariana Greenblatt, Lili Taylor, and Katherine Waterston. Set in 1988, the plot focuses on a masked killer who targets the prom queen candidates of Shadyside High School on the night of their senior dance.

Following the release of the original trilogy, discussions began about future films set within the same continuity. In October 2023, R. L. Stine announced further films to be in development, with the fourth installment being a standalone story and Chloe Okuno expected to direct. By March 2024, casting had been announced for principal characters, with McLeary and Palmer hired to adapt The Prom Queen and Palmer as director. Filming took place in Toronto and Hamilton from March to May 2024.

Fear Street: Prom Queen was released on Netflix on May 23, 2025, and was panned by critics, who named it inferior to the original three films.

On May 23, 1988, the senior class of Shadyside High School prepares for their prom. Lori Granger signs up to run for prom queen against the popular girl group nicknamed the "Wolfpack", consisting of ruthless queen bee Tiffany Falconer and her friends Melissa Mckendrick, Debbie Winters, and Linda Harper. Lori is considered an outcast by her peers due to rumours of her mother murdering her father, though she was deemed innocent. Vice Principal Brekenridge intends for the prom to reinvent Shadyside in spite of the town's poor reputation. The night before prom, candidate Christy Renault, who is also a local small-time marijuana dealer, gets a firefighter axe swung into her shoulder and is killed by a masked assailant.

The following day, Lori attends prom with her best friend Megan Rogers. Later, Megan stages a prank using a moulded copy of Tiffany's head, creating a rift between her and Lori. Meanwhile, Linda and her boyfriend Bobby are mutilated and killed by the assailant in a nearby classroom. Lori receives flowers from an anonymous sender before Tiffany harasses her about her mother's past. Debbie and her boyfriend Judd head to the basement, where the assailant kills Judd, using an electric saw and electrocutes Debbie in the power room.

After Melissa helps Lori fix her makeup, Tiffany ends their friendship and ruins Melissa's dress with punch. Lori and Tiffany engage in a dance-off, during which Lori wins over the crowd and Tiffany is left embarrassed. Her boyfriend Tyler Torres breaks up with her and approaches Lori, who harbours feelings for him. Meanwhile, Melissa is killed in the girls' changing room by the assailant using a meat cleaver, revealing there are two masked assailants. Megan interrupts Lori, suspecting the disappearances of the prom queen candidates to be a serial killing carried out by Brekenridge's devoutly religious son, Devlin Brekenridge. Lori rejects Megan's theory and the two distance themselves.

Later, Megan investigates the basement where she finds the dead bodies of Debbie, Judd, and janitor Stoker. Lori and Tyler head to the auditorium where Tyler tries to initiate sex. However, the assailant plunges a kitchen knife into Tyler’s skull, killing him, and chases Lori throughout the dim lit halls. She finds Megan screaming in the basement, but they are locked inside by the assailant. After a brief chase, Lori and Megan escape through a window and rush to the gymnasium to warn everyone.

Lori is announced as prom queen just as she tries to warn the school. The assailant arrives and dismembers Claire, decapitates Gerald, and severs Principal Wayland’s arm, but he survives. Lori uses the tiara to stab the assailant in the eye, who is unmasked as Tiffany's father, Dan Falconer.
