Final Fantasy VII, a role-playing video game developed by Square (now Square Enix) and originally released in 1997, features many fictional characters in both major and minor roles. VII has been followed by multiple sequels and prequels, grouped into the multimedia series Compilation of Final Fantasy VII: these include the 2004 mobile game Before Crisis, the 2005 movie sequel Advent Children, the 2006 shooter spinoff Dirge of Cerberus, and the 2007 action game Crisis Core. Other media include spin-off books and the original video animation Last Order. The setting of Final Fantasy VII is a world that has been described as an industrial or post-industrial science fiction setting. It is referred to as "the Planet" in most of the games, and was retroactively named "Gaia" in some Square Enix promotional material.

VII follows Cloud Strife, a troubled mercenary who joins with an eco-terrorist group to stop Shinra from draining the life of the Planet to use as an energy source. As the story progresses, conflicts escalate and the world's safety becomes their central concern as new forces emerge to challenge the original group. Cloud and his team eventually face off against the game's antagonist, Sephiroth. Other important characters in the series include Aerith Gainsborough, a flower seller who becomes a good friend to Cloud; Zack Fair, Cloud's friend, a former soldier of Shinra and the protagonist of Crisis Core; and Vincent Valentine, a man made immortal by Shinra experimentation and the protagonist of Dirge of Cerberus. The conflict between Cloud and Sephiroth forms the core narrative around which many of the series' stories are built. Other characters include the Turks, a covert group which originally worked for Shinra.

The original characters were designed by Tetsuya Nomura, who had done monster designs for Final Fantasy VI and was chosen for the role after his designs impressed producer Hironobu Sakaguchi. Nomura was responsible for many of the characters and their stories. The scenario for the original game was written by Sakaguchi, Yoshinori Kitase and Kazushige Nojima. Nomura, Kitase and Nojima have been involved in other titles in the Compilation. The characters of VII have met with positive reception in contemporary and modern reviews, while their portrayal in the Compilation titles has been mixed: while Crisis Core was generally praised, the focus on secondary characters in Dirge of Cerberus drew mixed opinions from some, while their appearance in Advent Children was generally cited as confusing or poor for newcomers to the series. The entire cast, along with multiple side characters and villains, have remained popular among critics and series fans over the years, with many lists and opinion polls citing them as some of the best characters in the Final Fantasy series.
