Ghostbusters: Frozen Empire is a 2024 American supernatural comedy horror film directed by Gil Kenan from a screenplay he co-wrote with Jason Reitman. It is the sequel to Ghostbusters: Afterlife (2021), the fourth mainline installment, and the fifth film overall in the Ghostbusters franchise. The film stars Paul Rudd, Carrie Coon, Finn Wolfhard, Mckenna Grace, Celeste O'Connor, and Logan Kim reprising their roles from Afterlife, alongside Bill Murray, Dan Aykroyd, Ernie Hudson, Annie Potts, and William Atherton reprising their characters from the earlier films. Kumail Nanjiani, Patton Oswalt, Emily Alyn Lind, and James Acaster also join the cast. Set three years after the events of Afterlife, the veteran Ghostbusters must join forces with their successors to save the world from a death-chilling god in New York City who seeks to build a spectral army.

Following the success of Afterlife, Sony Pictures announced the sequel in April 2022, with Reitman returning as director. Co-writer and executive producer Kenan later took over as director that December, with Reitman staying on as a co-writer and co-producer. That same month, Rudd, Coon, Grace, Wolfhard, O'Connor, Kim, Murray, Aykroyd, Hudson, Potts and Atherton were all confirmed to reprise their roles. New cast members including Nanjiani, Oswalt, Lind, and Acaster were announced in March 2023, with principal photography commencing that month and wrapping in June. Dario Marianelli was hired to compose the film's score, replacing Afterlife composer Rob Simonsen. As the first film in the Ghostbusters franchise to be released following the death of the franchise's co-creator and Jason Reitman's father Ivan Reitman, who posthumously receives credit as a producer alongside his son and Jason Blumenfeld, the film is dedicated to his memory and celebrates the 40th anniversary of the first film.

Ghostbusters: Frozen Empire had its world premiere at the AMC 13 Theater at Lincoln Square in New York City on March 14, 2024, and was released in the United States on March 22 by Columbia Pictures (via Sony Pictures Releasing). It received mixed reviews from critics and grossed $202 million worldwide. A sequel is in development.
