Tekken: Blood Vengeance (Japanese: 鉄拳 ブラッド・ベンジェンス, Hepburn: Tekken Buraddo Benjensu) is a 2011 Japanese animated science fiction martial arts film directed by Yōichi Mōri from a screenplay by Dai Satō, based on the video game series Tekken published by Namco Bandai Games. The film places focus on the young martial artist Ling Xiaoyu, who investigates experiments involving a supernatural curse related with the Mishima family, while befriending a robot named Alisa Bosconovitch. The two meet the test subject Shin Kamiya, who is being sought by his former friend Jin Kazama and his father Kazuya Mishima, but is also being used by Heihachi Mishima to set a new family fight.

Satō was given freedom by the video game series' executive director Katsuhiro Harada to write the film, which led him to the idea of Blood Vengeance being a buddy film by two female characters from different generations of video games. Tekken: Blood Vengeance was released in the United States by Bandai Entertainment on July 26, 2011, and in Australia on July 27, 2011, in a special exclusive one-off screening. It was released in Japan on September 3, 2011, by Namco Pictures. The film was released on Blu-ray Disc (included on the disc of the video game collection Tekken Hybrid) in the United States on November 22, 2011, and in Japan on December 1, 2011. The 2D version of the film was also released as a standalone DVD on November 22, 2011, in the US, and December 22, 2011, in Japan. It was later included with the video game Tekken 3D: Prime Edition.

The film was praised for its visuals and fight sequences, but criticized for its short length and few characters who have little impact in the story. Nevertheless, the film attracted Western audiences upon release. It was often considered as one of the best adaptations based on the video game series.
