The sequel to John Wick: Chapter 3 – Parabellum (2019) and the fourth installment in the John Wick franchise, the film stars Keanu Reeves as the title character, alongside Donnie Yen, Bill Skarsgård, Laurence Fishburne, Hiroyuki Sanada, Shamier Anderson, Lance Reddick, Rina Sawayama, Scott Adkins, Clancy Brown, and Ian McShane. In the film, John Wick sets out to get revenge on the High Table and those who left him for dead.

Development of the fourth John Wick film, formally announced by Lionsgate in May 2019, was confirmed before the release of its predecessor. It is the first film in the franchise that was not written by franchise creator Derek Kolstad, with Hatten hired in May 2020, followed by Finch in March 2021. Principal photography took place from June to October 2021, and filming locations included France, Germany, New York City, and Japan.

The original release date of May 21, 2021, was delayed due to the COVID-19 pandemic. John Wick: Chapter 4 premiered at the Odeon Luxe Leicester Square in London on March 6, 2023, and was released in the United States on March 24. The film received acclaim from critics, with praise for its action sequences, cinematography, choreography, visual style, and performances, and has grossed $440.1 million worldwide, becoming so the highest-grossing film in the franchise, as well as the ninth-highest-grossing film of the year domestically in the United States.

A spin-off, Ballerina, is set for release on June 7, 2024, while a fifth film is in development.
