Bad Boys: Ride or Die is a 2024 American buddy cop action comedy film starring Will Smith and Martin Lawrence. The fourth installment of the Bad Boys film series, and the sequel to Bad Boys for Life (2020), it was directed by Adil El Arbi and Bilall Fallah and written by Chris Bremner and Will Beall. In addition to the duo, Joe Pantoliano, Vanessa Hudgens, Alexander Ludwig, Paola Núñez, Jacob Scipio, John Salley and DJ Khaled also reprise their roles from previous installments. Tasha Smith joins the cast as Theresa Burnett replacing Theresa Randle, who played the character in the first three films. The story follows Miami detectives Mike Lowrey and Marcus Burnett, who are attempting to clear the name of their late Captain Conrad Howard after he is falsely accused of conspiracy.

Following the opening weekend box-office success of Bad Boys for Life, Sony announced plans for a fourth Bad Boys installment, with Bremner returning to write the script; however, in April 2022, production for the film was reportedly halted due to the incident with Smith slapping Chris Rock at the 2022 Academy Awards ceremony and the subsequent investigation. Eventually, it was announced that the film was in pre-production in February 2023, with principal photography beginning on April 3, 2023 in Atlanta, Georgia and ending on March 4, 2024.

Bad Boys: Ride or Die premiered at Coca-Cola Arena in Dubai on May 22, 2024, and was released in the United States on June 7 by Sony Pictures Releasing under its Columbia Pictures label. The film grossed $404.2 million worldwide against a production budget of $100 million and received mixed reviews from critics.
