Ghost in the Shell: Stand Alone Complex - Solid State Society (Japanese: 攻殻機動隊 STAND ALONE COMPLEX Solid State Society, Hepburn: Kōkaku Kidōtai Sutando Arōn Konpurekkusu Soriddo Sutēto Sosaieti) is a 2006 science fiction anime film and part of the Ghost in the Shell: Stand Alone Complex series based on Masamune Shirow's manga Ghost in the Shell. It was produced by Production I.G and directed by Kenji Kamiyama.

The film is set in 2034, two years after the events of 2nd GIG. Togusa is now the team leader for Public Security Section 9, which has increased considerably in size. Section 9 deals with a series of complicated incidents, including the assassination of Ka Rum, a former dictator of the Siak Republic, which leads to a terrorist plot using children as vectors for a cybernetic virus. Investigations reveal that a hacker nicknamed "The Puppeteer" is behind the entire series of events.

The film, which had a production budget of 360 million yen, premiered in Japan on SKY PerfecTV! on September 1, 2006, and later aired in the United States on Sci-Fi Channel's Ani-Monday programming block on June 11, 2007. A stereoscopic 3D version of the film was released in 2011. The film received generally positive reviews, but was criticized for being dialogue-heavy and lacking in action, something many felt the Stand Alone Complex television series did a better job balancing.
