Library War: The Wings of Revolution (Japanese: 図書館戦争 革命のつばさ, Hepburn: Toshokan Sensō: Kakumei no Tsubasa) is a 2012 Japanese animated film adapting Library Revolution, the fourth and final volume of Library War light novel series by Hiro Arikawa, and a sequel to Library War (2008). Produced by Production I.G and distributed by Kadokawa Pictures, the film is directed by Takayuki Hamana from a script written by Kenji Konuta. The film follows the Library Defense Force protecting a novelist, who becomes the target of the Media Betterment Committee due to the resemblance of his book to a recent terror attack.

The anime film adaptation was confirmed in June 2011. Hamana and Konuta joined the staff in December 2011. The voice cast of the anime series confirmed their return to reprise their roles for the film in February 2012, with Issey Ogata and Megumi Han joining them the following month.

Library War: The Wings of Revolution had an early screening in Tokyo on June 5, 2012, and was widely released in Japan on June 16. The film grossed over $2 million at the Japanese box office.
