Psycho-Pass: Sinners of the System, also shortened to Psycho-Pass SS, is a trilogy of Japanese anime films based on characters who appear in the Psycho-Pass television series. The trilogy was first announced in 2018 and the films were released by Production I.G in Japan in early 2019 full under direction of Naoyoshi Shiotani. The films stars the talents of Ayane Sakura, Hiroki Touchi, Kana Hanazawa, Kenji Nojima, Kinryū Arimoto, Tomokazu Seki among others.

The first film, Case.1 Crime and Punishment (罪と罰, Tsumi to Batsu), focuses on Reinforcer Nobuchika Ginoza and Inspector Mika Shimotsuki as they investigate a prison filled with people living in cheerful life. The second film, Case.2 First Guardian, focuses on Tomomi Masaoka and Teppei Sugo as how they met following the death of Sugo's friends. The third and final film, On the Other Side of Love and Hate (恩讐の彼方に＿＿, Case.3 Onshuu no Kanata ni) focuses on the mercenary Shinya Kogami as he continues his life in Eastern countries while training a young girl seeking for revenge. While different writers handled the three films, director Naoyoshi Shiotani worked on the three as he planned this trilogy with hints about the narrative for the third season, Psycho-Pass 3. Anime Limited released the trilogy in English regions.

Critical response to the movies have been generally positive based on the narrative's focus on the main character's minds, most notably Shimotsuki's growth in the first, the tragic elements in the second and Kogami's reflections in the third. The trilogy earned ¥378,636,200 in box office and the home media release also achieved good sales. Two novels and three manga adaptations were also published by Mag Garden.
