Universal Soldier: Day of Reckoning is a 2012 American science fiction action film directed by John Hyams, who co-edited with Andrew Drazek, and wrote the screenplay with Doug Magnuson and Jon Greenlagh. It stars Scott Adkins with Jean-Claude Van Damme and Dolph Lundgren, who both reprise their roles from the first film, alongside newcomer Andrei Arlovski. It is the sixth and final installment in the Universal Soldier film series.

The film acts as a sequel to 2009's Universal Soldier: Regeneration, unrelated to the two television sequels and ignoring the events of the 1999 theatrical sequel Universal Soldier: The Return. In the film, former military man John awakens from a coma and finds out his wife and daughter have been murdered in a home invasion. John goes on a personal vendetta against the man behind the killings, revealed to be Luc Deveraux, the eponymous Universal Soldier from the previous films who has now become a powerful terrorist military leader.

Though criticized for its "brutal" violence, others gave high praise for its direction, action, and "haunting" atmosphere, with some comparisons made to the works of Michael Haneke and David Lynch. Day of Reckoning was first released on VOD in the United States before receiving a theatrical release on November 30, 2012. The film grossed $1.4 million against a production budget of $8 million. A reboot of the series has been in development since 2018.
