Crisis Core: Final Fantasy VII (クライシス コア -ファイナルファンタジーVII-, Kuraishisu Koa -Fainaru Fantajī Sebun-) is an action role-playing game developed and published by Square Enix for the PlayStation Portable.

The game is a prequel to Final Fantasy VII and is also the fourth entry to the Compilation of Final Fantasy VII series, which also includes the games Before Crisis: Final Fantasy VII and Dirge of Cerberus: Final Fantasy VII, as well as the CGI movie Final Fantasy VII Advent Children and the anime, Last Order: Final Fantasy VII.

Production is being overseen by Yoshinori Kitase, the director of the original Final Fantasy VII, with Hajime Tabata as the game's director and Tetsuya Nomura as the game's character designer.

The game will mainly focus around Zack Fair, a 1st Class SOLDIER, and Cloud Strife while he is a lowly Shinra Guard. Another character also present in the game is Aerith Gainsborough as she features in the trailer of the game.

This game appears to take place around the events of Nibelheim outlined in Last Order: Final Fantasy VII.
