Jin-Roh (人狼, Jinrō, lit. "Werewolf"), also known as Jin-Roh: The Wolf Brigade in its American release, is a 1999 Japanese action political thriller anime film directed by Hiroyuki Okiura (in his directorial debut) and written by Mamoru Oshii. Based on the first chapter of volume 1 of Oshii's manga Kerberos Panzer Cop, it is the third film (first chronologically) in the Kerberos Saga after 1987's The Red Spectacles and 1991's StrayDog: Kerberos Panzer Cops, and is the only fully-animated film in the saga.

Jin-Roh is set in an authoritarian postwar Japan in the saga's alternate history where Nazi Germany won World War II, occupied Japan (a member of the Allies in this timeline), and eventually denazified back into the Weimar Republic. Germany attempts to globalize and modernize Japan with a new government, but it increases poverty and class stratification that leads to civil unrest and the rise of "the Sect", an anti-government left-wing terrorist group. With regular police unable to handle spiking terrorist activity, the Japanese government forms the Capital Police paramilitary law enforcement agency and their Special Armed Garrison "Kerberos", an elite heavily-armed counterterrorist police tactical unit equipped with powered exoskeletons called "Protect Gears". The film follows Kerberos member Kazuki Fuse who, after witnessing a young terrorist he was ordered to execute kill herself in a suicide bombing, meets Kei Amemiya, who claims to be the girl's sister; the film follows Fuse and Kei's relationship in the midst of a violent interservice rivalry between Kerberos and the Public Security Division, the Capital Police's intelligence unit.

The film premiered on November 17, 1999 in France and June 3, 2000 in Japan. Bandai Entertainment and Viz Media licensed the film for an English-language release in North America and Europe. It has been relicensed in North America by Discotek Media, with a DVD released on April 29, 2014 followed by a Blu-ray on January 27, 2015. A live action Korean remake, Illang: The Wolf Brigade, was released in 2018, featuring a different setting and renamed characters but largely the same premise and plot events.
