The 10th Victim (Italian: La decima vittima) is a 1965 science fiction film directed and co-written by Elio Petri, starring Marcello Mastroianni, Ursula Andress, Elsa Martinelli, and Salvo Randone.

The plot follows veteran Big Hunt contestants Caroline Meredith (Andress) and Marcello Poletti (Mastroianni), who are respectively assigned the roles of hunter and victim for one such confrontation, which is complicated by their budding romance.

Like Petri's other films, The 10th Victim is a work of socio-political satire, while also combining science fiction themes with conventions of the commedia all'italiana genre.

In order to prevent a potential fourth war, those with violent tendencies are given an opportunity to engage in "The Big Hunt," the world's most popular form of entertainment.

Eager to maximize her financial gains, Meredith aims for a flawless kill in front of the cameras, having secured a significant sponsorship from the Ming Tea Company.

A variety of screenwriters worked on the script to varying degrees without receiving an onscreen credit, including Suso Cecchi D'Amico, Nate Monaster and Ernesto Gastaldi.

Ponti's lack of interest in the science fiction genre led to his mandating of more comedic elements in the story against Petri's wishes, including altering its original, pessimistic ending.

Backed by financial support from Joseph E. Levine's Embassy Pictures, filming took place primarily on location in Rome and New York City from June to September 1964; produced at the height of the pop art movement in Italy, Petri sought to create a vision of the future that juxtaposes that style's imagery with Rome's ancient and modern architectural structures, such as the Colosseum and the EUR district.

In the audio commentary for the film, director Jay Roach mentions on that a sequence was "inspired by The Tenth Victim", which actor Mike Myers interjects that it was "Stolen from.
